To be a good loser is to learn how to win.
The most effective way to do it, is to do it.
Expect problems and eat them for breakfast.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
Do not weep do not wax indignant. Understand.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
Strange as it may seem, no amount of learning can cure stupidity, and formal education positively fortifies it.
