Never complain and never explain.
It's always too early to quit.
After a storm comes a calm.
Either you run the day or the day runs you.
Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
The whole essence of good drawing - and of good thinking, perhaps - is to work a subject down to the simplest form possible and still have it believable for what it is meant to be.
