I worked odd jobs to survive for the majority of my early adult life. I "fell into" a career job that I was indifferent about, but excelled in. I got promoted 3 times in 5-6 years, made it to a position that had people scouting/headhunting me via Linkedin. Although I ended up hating the field, and the job I was able to; pay off all my debt, take care of my GF so she could pursue and finish up school, live a comfortable life with hobbies and middle class luxuries, and money wasn't an immediate issue. After 6 years, with debt gone, GF in a good position, I quit my job at the beginning of this year. I'm now going after what I want to do because I can't imagine myself doing something I hate for another 6, 12, 18+ years.
Without getting too lecture-y I say if you're still young (Mark you're still in your early 20s if I'm not mistaken?) and aren't in survival mode, take your time and think long term about what you want to do/be, and then start your path. The longer you wait the harder it becomes. I might be in the minority, but for the long term I rather work a decent paying job that I love and don't mind 10+ hour days compared to a high paying job where I wake up every morning bitching and moaning about going in. Thankfully my new pursuit is pretty good pay and something I'm passionate about.
