It's always too early to quit.

What you do today can improve all your tomorrows.

The dog that trots about finds a bone.

I can, therefore I am.

To know oneself, one should assert oneself.

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

Leap, and the net will appear.

Do not weep do not wax indignant. Understand.

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