I used to be a shithead graffiti kid when I was younger. I got arrested and was given a light sentence. Now, about a decade later, i kinda wanna get into it again, but with the intention of making art in public spaces, not simply for marking my territory. IIN? Should I go back to it?

...Somehow
For sure, go for it! Make yourself some goals because it seems like some of the better street artists out there who are dedicated to their craft, make some pretty good cash selling it.
