In the morning, I will write for an hour, after which I'll usually head to the studio to flesh out my ideas with a producer. Depending on the schedule, I might have a 2 hour rehearsal in the early evening. Then more writing before bed.

I would say, if you have a passion and a talent for something, don't let anyone make you feel like you have to rush to get an education. School will always be there. If you don't know exactly what your calling in life is, school is a great place to figure that out. Be bold. Be brave. Don't let others live your life for you.
This was a source of pride, but still a bit alienating at times. Just be understanding that your family might not understand all of the stresses you are under.
