if you seriously want to become a writer here is my honest to god opinion
do not tag on a fucking wall, anywhere, until you get good at tagging
stick to blackbooks and writing on cardboard and pieces of wood in your backyard
when you can do good enough without embarrassing yourself, THEN go out and write.
dont hit the town just being an eyesore
if youre going to do it...get your style and your can control and control of markers down correct and meet a writer who can mentor you and teach you. stay away from the walls until you develop a style.
theres enough wack writers out there, dont add to it
