It's always too early to quit.

If you think you can do it, you can.

I can, therefore I am.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

Leap, and the net will appear.

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

The dog that trots about finds a bone.
