"The past is never dead. It's not even past."

"The most powerful tool in computer science is not the computer itself, but the human mind."

I will hazard a prediction. When you are 80 years old， and in a quiet moment of reflection narrating for only yourself the most personal version of your life story， the telling that will be most compact and meaningful will be the series of choices you have made. In the end， we are our choices. Build yourself a great story.
