To know oneself, one should assert oneself.

You never know what motivates you.

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

Know or listen to those who know.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

The secret of getting ahead is getting started.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.
