The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
Quality is not an act, it is a habit.
If you think you can do it, you can.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.
