Only the educated are free.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
I have had many occasions this year where I questioned and second-guessed my decision in a game, but it comes down to learning from mistakes and being accountable for what you did right or did wrong.
