Never complain and never explain.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
The most effective way to do it, is to do it.
It's always too early to quit.
A little learning is a dangerous thing, but a lot of ignorance is just as bad.
