I believe in two principles: Your attitude is more important than your capabilities. Similarly, your decision is more important than your capabilities!
A leader should never compare his technical skills with his employee's.
If you view everyone as your enemies, everyone around you will be your enemies.
Life is so short, so beautiful. Don't be so serious about work. Enjoy the lives.
Giving up is the greatest failure.
No matter how tough the chase is, you should always have the dream you saw on the first day. It'll keep you motivated and rescue you (from any weak thoughts).
