Only the educated are free.
Problems are not stop signs, they are guidelines.
Never complain and never explain.
The wise does at once what the fool does at last.
Know or listen to those who know.
Either you run the day or the day runs you.
The most effective way to do it, is to do it.
Go for it now. The future is promised to no one.
If you've got a talent, protect it.
Wherever you are - be all there.
