It's always too early to quit.

The wise does at once what the fool does at last.

The dog that trots about finds a bone.

If you're going through hell, keep going.

Go for it now. The future is promised to no one.

The most effective way to do it, is to do it.

Leap, and the net will appear.

Never complain and never explain.

Be thine own palace, or the world's thy jail.
