To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

The most effective way to do it, is to do it.

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

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.

Never complain and never explain.

Wherever you are - be all there.

Begin to be now what you will be hereafter.
