I think College is the way to go. As mentioned, it'll prepare you for the world you actually live in much better than pioneering will.
I did NOT go to college because I of course thought "the end was near", that was in 1983. Many many jobs are out of my reach without a degree and I eventually decided the only way I'd get into the business world I wanted to be in was to work for myself. I look for available jobs from time to time and even though I have alot of experience and success now, without a degree I'll just be skipped over for many jobs. It would be nice to know I had something to fall back on, but I'm not sure that I do.
Also, I knew an older couple a few years ago in KY that pioneered together all their lives, no college, never had kids, because "the end was near". Well, now they're in their 80's and he's losing his mind and making her life miserable and they have no children or money to sustain them. Did the congregation help these long time devoted JW's? Not more than driving them to some doctor's appointments and visiting them now and then. They put their all into the org and now they're dropped when they're no longer useful. It's very sad.
Oh, and don't overlook the social stagnation that can happen by staying away from people because they're not JW's. It's not fun trying to learn how to interact with people and make friends when you're 40 when you should have learned years ago.
