After a storm comes a calm.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
Go for it now. The future is promised to no one.
Never complain and never explain.
Be gentle to all and stern with yourself.
Science is a differential equation. Religion is a boundary condition.
