My best friend wants to join the Marines ASAP, and wants me to come with him. I'm 19, stopped going to college because I don't know what I want to do when I get older. I was in for computer science, but I can't sit behind a computer and program shit all day. I don't really know what I want to do, but it's going to be something working with my hands. My friend wants me to join him in Aviation Maintenance, which doesn't sound bad at all. I'm 6'2", 245lbs (big gut kind of 245lbs). Recruiter told me today that I had to lose at least 25lbs or so before I can go to boot camp, but I'm not sure if I even want to join. It sounds badass, but I'm sure I could find something else to do without joining the marines. Basically, I'd be joining the marines to get some structure in life, and to try to get myself started towards a career. I'm not good with lots of change, and I'd go nuts not being around my family and other friends. Right now i'm running a lot and working out and eating mostly tuna and peas and drinking a ton of water to try to lose the weight, but my friend is waiting to go to boot camp until I lose the weight. I don't know for sure what I want to do, and I feel like a dick for keeping him waiting for something that i'm not even positive i'm going to end up doing. Can someone help point me in the right direction? Give me some advice?
