Personally, it depends on what you really want to do. I know that's very vague, but let me explain. See, I am a creative writing major (or am currently in my third year of schooling to get one) so in your current situation, I would keep living with my brother so I could keep writing and trying to get something published. I don't know if I'll have that kind of option when I finish my degree, so I might be a tad bias

And as mentioned by someone, teaching might seem like a good idea until you can get something out there, if that's what you want, but I've heard it can really take the time from your life you would otherwise need for writing. So it should only be done in moderation as a result if at all possible. Now, once again, this is just my opinion, and based on the fact that I want to be a published writer almost more than anything else in the world, so I'm willing to make some potentially stupid decisions to obtain that goal.

So take it with a grain of salt and pepper.
