What is your motif of living here?
Enjoy your life. Don't sacrifice your fun. Don't waste time on computer game which you gain nothing after playing, only the feeling of emptiness.

Exploring the universe is my earliest dreams. When i grow up, i was thinking about winning a first Nobel prize for my country Malaysia. And now on, i find those ideas nonsense. What should i do?

When i read about world unfairness, climate change, tragedy of country or poor people, i am thinking what can i do to help them?

I hope that what i've studied can help me to reduce the pain of the world. I would like to see that my work really contribute to the world.

What should i do?
1. Find a professor whose work can satisfied this need.
2.
