You don't make good decisions when you're sick.
If you must have motivation, think of your paycheck.
Great spirits have always encountered violent opposition from mediocre minds.
The road to hell is paved with works-in-progress.
There is no substitute for paying attention.
Acquire new knowledge while thinking over the old, and you may become a teacher of others.
Never give up and never face the facts.
An ounce of loyalty is worth a pound of cleverness.
Get happiness out of your work or you may never know what happiness is
Be sure you're right, then go ahead.
