I would have to say NO. Education will take you where ever you want to go in life. Once you stop learning, you stop living.
Should I leave school?
If you're talking about quitting school....absolutely not. You need an education to get anywhere in life. KFC won't even hire you without a high school education. Stay in school, get as much education as you can....your life will be much easier.
You need education don't leave school
No, education isn't everything, but you do need it to get as high as possible. If you don't like school, at least try to make it through High School, that way you have a bit more opportunities. But please don't give up, you don't want to regret it later on in your life. This world is all about education, even if school isn't necessarily the place where you can get it, but take advantage of it while you can.
