You never know what motivates you.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
It's always too early to quit.
If you've got a talent, protect it.
Who seeks shall find.
If you're going through hell, keep going.
Go for it now. The future is promised to no one.
Know or listen to those who know.
Daoist thought is the root of science and technology in China.
