The secret of getting ahead is getting started.
You never know what motivates you.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
If you've got a talent, protect it.
Never complain and never explain.
It's always too early to quit.
Be kind whenever possible. It is always possible.
After a storm comes a calm.
Go for it now. The future is promised to no one.
The human imagination has already come to conceive the possibility of recreating human society.
The product of the scientific imagination is a new vision of relations - like that of artistic imagination.
