Most people would probably say good because you would be filled with energy and youth forever but on the downside you'd also miss out on a lot of things adults get to do.
I would personally say bad because instead of being stuck in school or having to listen to your parents you could find your dream job, spend time with friends, travel, etc. You can't get a job as a child until you're 16 but you are still under your parents control. So I think that it would be bad.
How this helps! :)
