Decide early on wether you like Graffiti itself or the game. Two totally different mind sets, the trick is to combine them. In honesty, if you live in a tiny town where you are gonna get heated out, more likely your going to work on letters and style forms to pass your time.
Age is a huge thing. No matter what anyone says your experience of writing from your parents house and then your own flat will change you. So right now I think you need to decide wether its the feeling of your heart beating as you cop a tag, knowing your going to get in the shit but not giving a fuck, or the colours and shapes that come from refined practice that turn you on. For years I HATED graffiti itself man, fuck learning letters and being fancy I want to FUCK SHIT UP, WHOS THE KING! But after a while when your name gets gripped and your tags buffed, no one is chatting about you really. So dont be a legal whore and rely on your HOF flicks to big your year up. BALANCE. Graff is an illigal activity, all should feel a slight amount of guilt for permission walls. Take that the right way all.
