I can, therefore I am.
What you do today can improve all your tomorrows.
You never know what motivates you.
Be kind whenever possible. It is always possible.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.
Never complain and never explain.
Do not weep do not wax indignant. Understand.
A serious and good philosophical work could be written consisting entirely of jokes.
