It's always too early to quit.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

The secret of getting ahead is getting started.

The dog that trots about finds a bone.

If you think you can do it, you can.

What you do today can improve all your tomorrows.

Be kind whenever possible. It is always possible.

By failing to prepare, you are preparing to fail.
