Teachers used to yelled at me or take my notebook away whenever I doodled in class, saying it would get me nowhere in life and that it was nothing but a waste of time, but seeing what you've done with your doodles inspires me to fight back. The way everything comes together in your art is amazing, and it's like nothing I've ever seen. It's unique and exciting in it's own little way. The fact that you sometimes use a regular sharpie pen makes it all the better. Keep on doodling, sir, I'm sure you've affected a lot of aspiring artists with your doodles!
Scientifically, your teachers were dead wrong. It gives you a calm down, let's you relax your brain from the hard work they give you, that(ironically) sometimes doesn't even help the brightest students when it comes to future jobs. An example is Matthew Pattrick, or Matt Patt from the Game Theorists, who was an extremely good student who applied to a bunch of jobs with perfect grades, and was still turned down. His perfect grades didn't matter to them at all.
But art, it truly can take off. If you put the right amount of effort into it. But I'm not saying to completely ignore your grades. It's always a good idea to keep your grades up, for scholarships and the such. Art, though, can improve over time of practice and hard work, and you should always fight back when people try to stop you from doing what you love. Because you can change the word with a flick of your wrist and a pencil.
long as it ain't murder.
The line that says "it would get me nowhere" was yelled to me so many times during my childhood, there were times I had thoughts of stopping and just forget about everything related to drawing but when you love to do something, that something will always find its way back. I realized drawing will be part of me til' death that's why I draw, it's what I love to do and I enjoy it more than anything.
I'm always so glad I inspire people,,
Make art by heart fellaz!
