At 35 I'm definitely starting to feel more like a grown-up than I ever have. There's nothing in my life that is childish or whimsical. Having fun is fantastic and I never want to lose a sense of that - and also I think you have to have that to put into your work or else it's going to feel stiff.
When you are studying jazz the best thing to do is listen to records or listen to live music. It isn't as though you go to a teacher. You just listen as much as you can and absorb everything.
