Be thine own palace, or the world's thy jail.
Only the educated are free.
It's always too early to quit.
You never know what motivates you.
Without hard work, nothing grows but weeds.
To be a good loser is to learn how to win.
Never complain and never explain.
Know or listen to those who know.
If you're going through hell, keep going.
The most effective way to do it, is to do it.
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.
