It's a no brainer that if you can do something that you love, you'll do it. Especially if you're paid for it as well, cough YouTube cough. But you'll see a large majority of people creating content for YouTube or livestreaming on Twitch do it as a hobby of some sorts with an actual job on the side to support them.
In a sense, we learned about this in Week 2's CIU class. Whether we work as a freelancer in our field with a job on the side to support ourselves or go balls to walls and go without a side job and live on Ramen and instant noodles for the rest of your career. While eating instant noodles for years tends to save quite a bit of money, for myself, it doesn't sound all too appealing. Especially in my field which is Game Programming.
During the lecture, there was discussion about whether any of us would freelance, work at a studio or start our own studio. While many people in my class was unsure what they wanted to do, I was gravitating towards working at a studio since with what I've done so far, it seems logical to me. Before I came to SAE, I've been programming various tools on my website, rubbix.net, since Grade 9. So it kinda fits in with, I'm told what to do, then I go and implement it.
Working at a studio limits what I can do, but too me, a secure income appeals more to me than working for individual customers on a commision base, even though you have the grounds of charging more if you're a freelancer.
