i feel ya june. did the exact same thing and am in the exact same boat. i'm getting a job in the restaurant industry and going to pursue my shit anyway (music-recording and performance). overestimated or not, it's another good chance to start at the the bottom and
earn your way up.
do you feel compelled to do that "something else" no matter the sacrifice? is that "se" something that you struggle with or that comes out of the clear blue sky into your brain? do you feel insecure when you describe the details of that "se", or do you get a clear picture of what you're trying to communicate?
these questions should help pinpoint true intention within your heartmind.
