If you think you can do it, you can.
It's always too early to quit.
The dog that trots about finds a bone.
After a storm comes a calm.
Expect problems and eat them for breakfast.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
Who seeks shall find.
By failing to prepare, you are preparing to fail.
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.
