so right now I am in the army and I'm absolutely having it. one good thing about this however is that I have the option of going to college for free while I am in or when I get out. im 22 now and I will be 25 when I get out. im tired of feeling like im wasting my time here doing dumb shit and I want to do something that will actually make a difference in the world. the only downside and part of the reason that I am here is because I didn't know what I actually wanted to do with my life. what jobs or career fields can I start studying to go into that will actually make a positive difference in the world and make other people lives better.
