Never complain and never explain.

It's always too early to quit.

Know or listen to those who know.

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

If you think you can do it, you can.

What you do today can improve all your tomorrows.

Leap, and the net will appear.

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

Begin to be now what you will be hereafter.
