/ic/ - Artwork/Critique

Even if I'm a begginer, I want to draw EVERYTHING. Cars, aircrafts etc using perspective, people, faces, fucking proportions, then environments. Also, I want to master coloring and maybe one day, stylization. I know a little about each subject, even if I'm bad at it I just need to study. My problem is, I don't know how start and how organize my time for that. What would you recommend? How I make an efficent schedule? I know it will take time until my work start to look good. If I just focus in one subject I'll feel like I'm not doing enough, even if I draw 12 hours everyday.

Oh, and another thing. I own a "gaming" pc and a notebook for drawing. My pc stays on the table and the notebook is always changing location, I have no place for it in my bedroom. But there's an empty room which I could use for drawing. The problem is, I can't get out of my comfort zone, I don't feel like taking my notebook and going to another room, since my bedroom is so comfortable. Do you thing setting a bed on the empty room would make me stay there more often?

Sorry if it was a long text, I need to improve fast. 22 of July I'm entering in a "contest".
