Know or listen to those who know.

To know oneself, one should assert oneself.

Either you run the day or the day runs you.

Be gentle to all and stern with yourself.

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.

If you think you can do it, you can.

Things do not happen. Things are made to happen.
