I don't remember who said it or when it was said, but some guy once said that advice is peoples' way of living vicariously through you. Keep that in mind and your grain of salt in hand when getting ANY advice.
I'm 22 and just got out of college this May. I've got a BBA in Business Management.
I got the BBA for two reasons. First, I'm pretty decent with business. I've run a few of my own and have made side spending money for myself. Second, I did so because you can't really go wrong with a business degree.
In 1-2 year's time, I'm going into law school. I'm not going in immedately because I need to save money to assist with tuition and because I want to get out in the real world for a bit. (Academia is [b][i][u]very[/u][/i][/b] far removed from real life.)
My advice is not to do what I'm doing. I also advise you to not do what anyone else here says to do.
You should do what YOU like to do. You're 16; only two years away from being an adult, being able to buy your own AR-15, being eligible for selective service... You get where I'm going. You know a lot, but you don't know everything yet. Take stock of what you like. More importantly, take stock of what you DIS-like. (If nothing else, you'll know what NOT to do.)
Right now, you've got a good business going. If you'll do even one car a day, you're making at least $85 per day. Not bad at all for a 16 year old. Even better when you consider that you could be flipping burgers or being a checker at a supermarket.
If you truly like the military life, go for ROTC and then into the armed forces. However, if you're doing detailing because you like your FREEDOM to be your own boss, you may want to reconsider. Perhaps you could go straight into LEO work instead. After a bit of that, then go for the FBI.
Hmm. When I was 16.....
1. I should have gone to the career counselor more often. Take a few of those interest surveys. Use them, but understand that they're not gospel.
2. I totally avoided the idea of joining the military like the plague. I'm VERY independant and I do NOT take orders well. I hate being told what to do-- I'll figure it out myself. Plus, Klinton was the Commander-in-Chief. If you truly want to go into the military, fine. Just remember that going from soldier to peace-keeper to political pawn is VERY simple now-a-days. (What happens if the Democrats take back power in 2004? Suddenly, you're keeping the peace under some UN security force in a godforsaken hole.....)
3. I was clueless. You do a LOT of mind-changing from 16 to 17 to 18 and on and on. Nothing wrong with it, either. You're just getting a better idea of what you want and don't want from life.
Hmm. Well, that's it. Good luck to ya! (And, if you get to be FBI director some years down the road, try to restore some order to that agency.) [:D]
