>>1534888Hey me too! I have ADHD too.
The way that I found to combat it, is to focus on drawing rule34 (cartoon porn). Finding sexy characters that I'm attracted to, and drawing porn of them. That was the only way to keep me interested enough to complete a doodle.
Just practicing drawing clean curves* with pen and paper (fuck tablet + digital, get good at TRADITIONAL art first) is very boring, that's why instead of drawing a nice clean curve, I'm actually drawing the nice clean outline of breasts of that character that I like. Or the lip outlines of her plump puzy.
* There are only three possible types of curves that you need to learn: the serpentine, the cusp and the loop. Mathematically they are the only possible ways a curve can be and that you'll ever draw.
If you master these three types (by doing lots of exercises on paper), then anything you try to draw (boobs, thighs, big bubble butts, feet) will be easy as they're just a combination of these curves.
