I think everyone faces this in their life at one point. You can choose to do what's been set as the norm and go on with your life, but it might not make you happy, or you can choose to do what makes you happy and not make a lot of money. Choosing to just do what makes you happy isn't always easy and you have to make sacrifices in the end, but it will make your life 100% better. There's so many talented artists on Newgrounds and you're one of the best, so I bet you'll find success as long as you keep at it.

I read this last night but didn't get a chance to comment on it until today. I pretty much have the exact same sentiments that you posted here. Anyway, I think everyone else's comments summed it up: go for what makes you happy.
You definitely have the skill/talent to pull it off, in my opinion. Good luck!
