I sing and play guitar for people in bands.
Wake up, warm up vocals, and always practice a new chord on my guitar. Meet with the band and rehearse. Write music and have fun with my friends in the band and who help out.
I recommend you have fun everyday in high school.
Here's the first step for high school students
Have fun in school with your friends and do good. Sure you will be leaving somewhere right after high school but do good. It's very important and cherish every moment with your friends. The hardest thing to do is leave and once you leave you wont see them for a really long time.
"You should focus on school and get a job where you can get a good paycheck and support your family instead of focusing too much on guitar and singing."
