It's always too early to quit.
After a storm comes a calm.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
Leap, and the net will appear.
Never complain and never explain.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Who seeks shall find.
Expect problems and eat them for breakfast.
When I tried to play something and screwed up, I'd hear some other note that would come into play. Then I started trying different things to find the beauty in it.
The worst advice I ever received from my dad was to play by the book.
