To be pleased with one's limits is a wretched state.

You may feel like dwelling on your limits or your fears. Don't do it. A perfect prescription for a squandered, unfulfilled life is to accommodate selfdefeating feelings while undercutting your finest, most productive ones.

The only limits to the possibilities in your life tomorrow are your "buts" you use today.

The only way of finding the limits of the possible is by going beyond them to into the impossible.

Selfknowledge is best learned, not by contemplation, but by action. Strive to do your duty and you will soon discover of what stuff you are made.

In each of us are places where we have never gone. Only by pressing the limits do you ever find them.
