To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

I can, therefore I am.

What you do today can improve all your tomorrows.

You never know what motivates you.

Either you run the day or the day runs you.

The dog that trots about finds a bone.

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

Know or listen to those who know.
