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

What you do today can improve all your tomorrows.

Know or listen to those who know.

Never complain and never explain.

Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

I can, therefore I am.

If you're going through hell, keep going.

To know oneself, one should assert oneself.
