I am an upcoming senior (Hurray!) and I want to make some more money to start saving up. However, I teach (for very little, plus it’s not for long. I get like $36 paychecks) dance classes twice a week, I tutor elementary school children one afternoon for an hour, I have cello lessons one night a week for an hour. And (finally, haha) I volunteer feeding the homeless every Friday.

I know I have a busy schedule, but I want to make more money to save and so I can have more to spend. I also want to help pay for my expensive ($70 a lesson!!!) cello lessons.
Any recommendations?
