Do not weep do not wax indignant. Understand.
To know oneself, one should assert oneself.
Never complain and never explain.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
Well done is better than well said.
It's always too early to quit.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.
If you're going through hell, keep going.
I do engineering, not religion.
