What you do today can improve all your tomorrows.

Never complain and never explain.

The secret of getting ahead is getting started.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

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

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

To know oneself, one should assert oneself.

You never know what motivates you.
