Yeah thats definately a tough decision to make. I know I had to make alot of the same in my life. You just gotta take a seat, weigh out your choices, and figure out what is the best thing to do. I think everyone hear can attest to losing alot to continue on with this addiction. Go to school, get a good job, maybe do a legal on the weekend; or instead bomb the fuck out of your city everynight, even with the 8 am courtdate later that day, while getting mad respect from fellow writers. Just remember, graffiti wasnt cut out for everyone.
In any case, good luck.
