I started working at 13! (forced by my mother) I'm now 43 and have worked several, SEVERAL jobs over the years. What I learned from starting work early is that, you have to work, my dad had great work ethic and that may be part of why I was obsessed with work. When I was a junior in high school, I was working 40 hours a week during school and 60 hours a week during the summer. Don't let it affect your grades and make "you" time during which you have a blast. Good luck!
