It's always too early to quit.

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

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

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

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

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

Leap, and the net will appear.

Well done is better than well said.
