Never complain and never explain.
By failing to prepare, you are preparing to fail.
Without hard work, nothing grows but weeds.
Do not weep do not wax indignant. Understand.
Wherever you are - be all there.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
Well done is better than well said.
Know or listen to those who know.
If you're going through hell, keep going.
Although you may spend your life killing, You will not exhaust all your foes. But if you quell your own anger, your real enemy will be slain.
If you desire ease, forsake learning.
