hell no. do what you want, although you'll have to mature faster but its not bad, as long as your parents weren't paying (IMO).
No, not at all. Everyone is different. College, however, is pretty much necessary in today's society. I would consider online classes or a community college. Times are a-changin'!
No, not everyone is a scholar. Have a back up plan on how you will earn a living. College graduates earn far more in a lifetime. good luck.
Meh. I dropped out of high school, dropped out of college, now I'm employed as a contract computer programmer and have worked in lead roles for Fortune 500 companies on critical projects. It depends who you are.
Why is it not for you?
