Dream Jobs

Ok so one of my good friends is planning on joining the military now. That's just something I simply don't understand.
At all.
I guess there is the allure of the military and all, but I don't understand why you would dedicate your whole life to fighting when there are so many better things out there to be doing!
My personal opinion of dream jobs: make it something you would do for free. No cash, no nothing. Then get good enough at it that people will actually pay you for what you do or make. Be it playing music, baking, writing, painting, singing, drawing... WHATEVER! Anything that you love doing but people will pay you for. That there is a dream job. Doesn't happen you say? Not usually you say? Usually doesn't mean never.
Check this - Sam R-P - The musician brother of one of my best friends. When he still lived at home he played constantly just for fun and it sounded great! So, he published an album and is going to Berklee School of Music! John Green, he writes books and makes YouTube videos for a living! Name a band. They play music to huge crowds! But I'm willing to bet they would play even if there wasn't a soul listening. That is what people should strive for. That is what a dream job is. Don't settle for some monotonous desk job. Go out there and make something of yourself! Show the world what you love to do!
