It's always too early to quit.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Never complain and never explain.
If you can dream it, you can do it.
By failing to prepare, you are preparing to fail.
Who seeks shall find.
If you're going through hell, keep going.
Only the educated are free.
Be thine own palace, or the world's thy jail.
It is not worth an intelligent man's time to be in the majority. By definition, there are already enough people to do that.
