Do not weep do not wax indignant. Understand.
The dog that trots about finds a bone.
It's always too early to quit.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
You never know what motivates you.
Always desire to learn something useful.
Quality is not an act, it is a habit.
If you've got a talent, protect it.
By failing to prepare, you are preparing to fail.
There's always a learning curve, where you've got to learn what your subject is all about.
