Never complain and never explain.

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

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

I can, therefore I am.

Begin to be now what you will be hereafter.

If you think you can do it, you can.

Leap, and the net will appear.

What you do today can improve all your tomorrows.

Know or listen to those who know.
