this is addressed to toys and new writers of all breeds:

before you start, ask yourself: why am i doing this?
the answer cannot be any of the following (and many more that I haven't listed)
-because i want to destroy shit
-because i did it in marc ecko's getting up, and i thought it was cool
-because i'm "gangster"
-because i'm a "rebel" or "punk"
-etc...
what you NEED to consider is that if you leave the house with cans, markers, stickers, and no thought or motivation in your head, you'll burn out. sorry, but it's true. you'll also make crappy graff, be a terrible writer, and of no benefit to our movement and hobby. often, people who have this problem change names constantly, searching for the spark of their own self-motivation, and it's almost always futile.
instead, what i'm saying is, before you start, set goals, and continually self-improve. it's crucial that if you're gonna be serious about this that you make it your GOAL to always be putting something nicer and nicer out there; i'm not saying pieces only, you can bomb, but if you do, make it NICE! no dusty fills and drips and shit... make it look proper. having 100 shitty fills is gonna give you temporary fame but in the end hurt you, because you'll be remembered as a vandal, not an artist. true artists have their shit looking clean, proper, and legit each and every time... which believe it or not is one of the hardest things to do.
it's not as fast as destroying an entire block, but think about it. what would YOU like to be remembered as?
