If you think you can do it, you can.
After a storm comes a calm.
The wise does at once what the fool does at last.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
In regard to music, I just think that it's always best to have an attitude of being a perpetual student and always look to learn something new about music, because there's always something new to learn.
