I got two sides this....If you draw and never paint even if your style is developed on paper, you still wont be able to paint it for shit on a wall so you'll have shaky lines and drips ect.. but yes draw way more than you paint at first.. it will switch eventually into more painting than drawing over time. but not need to go out and "kill shit" at first. I know everyone else seems to think its gay but when your first starting having a little plywood board isnt a bad thing you can practice and see what looks good and gain a little sense of how take a sketch from paper to a wall and not make your area look like shit. but then again a lot of people would disagree with that...Also learn your areas history before you learn about "Mad Hiphop youtube crews" like SDK..feel free to comment back..
