Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
It's always too early to quit.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
The dog that trots about finds a bone.
I dropped out of school for a semester, transferred to another college, switched to an art major, graduated, got married, and for a while worked as a graphic designer.
