Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
Always desire to learn something useful.
If you've got a talent, protect it.
It's always too early to quit.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
Either you run the day or the day runs you.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.
By the fulfillment of my legal and moral duty I think I have earned punishment just as little as the tens of thousands of dutiful German officials who have now been imprisoned only because they carried out their duties.
