Never complain and never explain.
Wherever you are - be all there.
If you're going through hell, keep going.
Do not weep do not wax indignant. Understand.
Only the educated are free.
By failing to prepare, you are preparing to fail.
Leap, and the net will appear.
You never know what motivates you.
To know oneself, one should assert oneself.
Who seeks shall find.
Daoist thought is the root of science and technology in China.
