I can, therefore I am.

After a storm comes a calm.

Do not weep do not wax indignant. Understand.

Be gentle to all and stern with yourself.

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

You never know what motivates you.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.
