Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
You never know what motivates you.
The wise does at once what the fool does at last.
To be a good loser is to learn how to win.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
If you've got a talent, protect it.
Be kind whenever possible. It is always possible.
Be thine own palace, or the world's thy jail.
Aging is an inevitable process. I surely wouldn't want to grow younger. The older you become, the more you know your bank account of knowledge is much richer.
