When you take a man as he is, you make him worse. When you take a man as he can be, you make him better.

Winston Churchill

Success is not final, failure is not fatal: It is the courage to continue that counts.

Michael Jordan

I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed.

Clint Eastwood

Respect your efforts, respect yourself. Self-respect leads to self-discipline. When you have both firmly under your belt, that's real power.

Steve Jobs

I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. And that is as true for your work as it is for your lovers.

CPT Step 5: Data Analysis Proposal

             Now we are living in 21st century and the effectiveness of technology, such as mobile phones, has been discussed or a long period of time. Some people may think that these technology has negative effects. One of the most representative case is using mobile phone while driving. This action will distract driving, results in the fatal accidents. There are a lot of functions, as we call them smartphones. Mobile phone’s basic functions—texting and calling —are the major reasons that lead the distracted driving which causes a fatal car crash. In order to prevent the car accident caused by the distracted driving, governments made the law prohibiting texting while driving including Canada. However, all of these depend on drivers and their attitude. My research focuses on proving that texting ban in Ontario will not reduce significant amount of the death from collisions with the similar penalty with the United States. The results of my survey (primary sources) show that most people think that mobile phone is part of their life and it’s hard to live without it. A lot of people still use mobile phone even after the law prohibiting texting while driving has been made. My secondary sources show that the law regarding distracted driving is not effective in the United States, which indicates that the law in Canada will not be effective with the similar penalty with the United States. For instance, in the United States, texting ban were associated with a 3% reduction in traffic fatalities. On the other hand, the car crash regarding distracted driving increased in some States. I will expect that most people, especially old people will agree on the riskiness of using mobile phone while driving since their child’s driving habit will take an important roles in their lives, and this will lead to the necessity of strengthening the texting ban.

             After collecting the data and show it in the form of pie chart, we will see that about 80% of the people think that texting ban in Ontario is effective enough. However, majority of people still believe that strengthening the law will decrease the huge amount of a fatal car crash regarding distracted driving. I expect that, as time passes, the percentage of people who agree will keep increasing and disagree will keep decreasing due to the increasing amount of technologies that are invented and are used in more ways in our society. Also, we know that nowadays most people have their own mobile phones and it is hard to live without them. However, using mobile phones while driving affect not only your life, but also others’. Therefore, effectiveness of texting ban is very important in our society and helpful to make a safe environment for everyone.

[Mediterranean] Me Va Me

☆Hot Place Review☆

Mediterranean Restaurant

"Me Va Me"

I visited downtown Markham after I went to the BMW test drive events.

After the test drive, I was so hungry and looking for the restaurant.

Then my friend told me that he knows the Japanese ramen place and it's pretty good.

So, we went to that place.

It's located in the same building with Cineplex Cinemas Markham and VIP.

Raman place is on the second floor so we need to walk.

When my friend and I were heading to the Japanese restaurant,

I found Mediterranean restaurant called Me Va Me.

Since I really like middle eastern cuisine, I literary begged him to go to this place instead lol.

Restaurant was really nice, looking good.

All of the employees were kind.

Pita breads are free of charge for appetizer.

I ordered chicken schnitzel with greek salad and rice.

Schnitzel sauce was AMAZING!!!

Salad was fresh and chicken schnitzel was crispy.

It cost about $20

My Rate: ★☆

 My friend ordered chicken shawarma in plate with Me Salad and wedge potatoes.

Me Salad was good.

Wedge Potatoes were crispy and good as always.

Shawarma was tasty as well.

It also costs about $20

My Rate: 


Price range was good and foods were tasty.

Employees were nice and kind.

Kitchen is kept clean and it's good that the customers can see the kitchen directly.


Food Quality: ★☆

Restaurant Quality: ★☆


General Review

I recommend this restaurant for those who want to try the Mediterranean cuisine with friends.

Considering that this place is kitchen express, I don't recommend this place for dating.

For dating with better restaurant quality, visit Me Va Me, located on 7000 Bathurst St, Thornhill, ON L4J 8S3, which is actual restaurant.

Town+Country BMW Test Drive Event!

Long Time No See Guys!!!

I am finally back XD

Last Thursday,

I went to the Town+Country BMW for the test drive event.

It's been almost 6 months that I got my G2 license.

So I decide to buy a car.

There are lots of selections.


I decide to buy one either BMW 3 series, X1 28i, or Toyota RAV4.

So I did the test drive 2017 330i and 2017 X1 28i with M Sport Package.

Because there was a test drive event,

a lot of people were there.

Since I booked the test drive a week before I go,

I didn't need to wait for the test drive.


I didn't take the picture of the cars that I did test drives.

For me, honestly, 2017 X1 28i wasn't good.

It was a great car,


my driving style and the car didn't match.

On the other hand,

2017 330i was great.

It was really quiet, driving was fun.

So I'm probably gonna get BMW 3 series or Toyota RAV4.

I also got a small gift from BMW.

This is the product that helps you to find the key when we lose it.

You can simply download the app and connect this device via bluetooth with your phone.

Then whenever you lose your key, your can simply go to app and make this device to make a sound.

I also got BMW purchase reward which I can get $750 discount for 2017 BMW 3 Series.

Thanks to Town+Country BMW


Sammy Liu.

Data Management CPT: Data Collection Proposal

Data Management CPT: Data Collection Proposal


             Twelve per cent of deaths of fatal car accidents is due to distracted driving in the United States. The law that was placed in 2008 regarding distracted driving has not reduced the overall amount of crashes ever since, which indicates that the texting ban in Ontario will not reduce the death from collisions with the similar penalty with the United States.

             The topic that I am choosing to research about deals with the law prohibiting texting while driving. These articles prove that texting ban is effective among most of the people, but they also show how they affect the limit of the texting ban. This indicates that not all articles have the same result. It was effective in some States, but others didn’t. That is the reason why I will do more research to see how many people think that texting ban in Ontario is effective after Ontario made the law prohibiting texting while driving in 2015. Also, I will try to find out why they agree or disagree. The variables that I will be focusing on are the time that people use their mobile phone while driving, what they do with a phone in a car, and how the law changed their mobile phone usage while driving. From this variables I could observe how much time people use their phone while driving, the main reason of using phone, and the effectiveness of texting ban. I will determine the situation that the United States faced after texting bans and how Canada should handle the law prohibiting texting while driving based on the data that I will collect.
