Enjoy high school, there isn’t any real experience you can gain from working as a food servant, bus boy, or anything else that is going to pay you minimum wage. That’s not to say that any of those are bad jobs, but I’d venture to say that you should spend your youth building the skills and talents that allow you to earn more than minimum wage. The only job you can have in high school is as a construction laborer, so you can learn the value of a good education.
Now college you have a ton of doors open to you to work and get some real experience, so work. Plus you’ll have extra money and it’ll help you transition to a real job.
