Be gentle to all and stern with yourself.

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

Know or listen to those who know.

What you do today can improve all your tomorrows.

Begin to be now what you will be hereafter.

The dog that trots about finds a bone.

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

To know oneself, one should assert oneself.

If you're going through hell, keep going.
