Know or listen to those who know.

The secret of getting ahead is getting started.

If you're going through hell, keep going.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

Begin to be now what you will be hereafter.

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

Either you run the day or the day runs you.

The dog that trots about finds a bone.
