Be kind whenever possible. It is always possible.

Never complain and never explain.

To know oneself, one should assert oneself.

You never know what motivates you.

Know or listen to those who know.

Be gentle to all and stern with yourself.

Be thine own palace, or the world's thy jail.

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

What you do today can improve all your tomorrows.
