Be thine own palace, or the world's thy jail.
Know or listen to those who know.
I can, therefore I am.
Either you run the day or the day runs you.
If you can dream it, you can do it.
It's always too early to quit.
Go for it now. The future is promised to no one.
After a storm comes a calm.
Wherever you are - be all there.
Problems are not stop signs, they are guidelines.
They should hold themselves absolutely upon the immovable foundation of truth and nature, whereby alone they can save themselves from misapprehensions and from the danger of being entirely carried away from reality into mere dreams and fictions.
