I haven't listened to much Phineas Newborn Jr., but I love this quote:
Before we went to Europe in 1979, I'd asked Phineas what he considered the most important thing for a young musician to keep in mind.
'Stay young at heart. That's the right idea as far as I'm concerned. Play young at heart. Play the way you feel. A thing of value outlasts a thing that has no value. Attempt to produce things of value as you go along. If it's worthless, it won't last; if it has value, it generally does--an eternity, almost, in minds and hearts.' (Phineas Newborn, Jr., quoted in Stanley Booth, Rhythm Oil)
