Good Ol state of Texas, land of murica, freedom, and more guns than god... I honestly remember the first time I shot a gun, then shot so bad it ricocheted into the wall close to one of the other stands, certifying that I was a terrible shot, so I tried other things, and boxing worked out well, and paired with having to do a lot of lifting and movin heavy stuff like cargo as a teen to earn some money. Not only was that good job experience, it helped build some muscle and good grip strength, which can come in handy for quite a few things!
And while I could of gone for some of the more normal jobs to start out with after I turned 18, I wanted to go as far as possible, wanted to be a paramedic so I could help people on the front lines.... that dream unfortunately didn't turn out the way I really wanted it to...
Mostly helping teach other medical students, thanks to having a pretty decent amount of experience with medical training and knowledge, and can help give pointers on what and how to do some things within the medical field, though I can't really help with physical stuff directly, which is a shame, but well, sometimes you gotta get into a sink or swim situation to learn some shit and well.... sometimes that experience can really push someone past their limits
As for spendin... well, the extra money helped me pay for some boxing lessons, and well, surprisingly I was pretty good at boxing, so I've been able to win a few matches as well, earning a nice pretty penny! maybe I should try a few matches someday...
