With any new skill you need to be willing to sink a lot of time into it. And you need to be fine with being absolutely terrible at it in the beginning.

I usually tell people who want to learn to draw to go to http://johnkcurriculum.blogspot.com/2009/12/preston-blair-le..., get the Preston Blair book, and start doing these exercises by master animator John K (creator of 'Ren & Stimpy'). You will get a lot better, a lot faster. These exercises focus on simple cartoon characters who wear a lot of their construction on the outside; once you can draw cartoon characters, you can keep drawing more of them if that's your thing, or you can build on top of that and start learning anatomy and drawing more complicated characters. (Or do both.)

There's other well-regarded drawing courses on the internet and someday I should probably pick a new one to send noobs to, what with John K kind of being an asshole - but I learnt a hell of a lot when I worked under him, and he is really good at teaching this stuff.

Most of what I know about drawing more complicated figures came from a combination of Bridgeman's "Constructive Anatomy" and Loomis' "Figure Drawing for All It's Worth", and a life drawing teacher who hewed very closely to Glen Vilppu's drawing manual. If you can fit some life drawing classes into your life then TAKE them, you will learn a ton.

Also: Make a space in your life to do this. I ride the bus a lot, and before the advent of smartphones, I'd have little to do to amuse myself besides stare out of the window, read a book, or pull my sketchbook out and draw. Maybe draw some idea floating around my head, maybe draw something I glimpsed out the bus window, maybe something based on my fellow passengers, maybe just some cubes, or the hand I wasn't drawing with. I got a lot of practice in without feeling like I was making myself "practice". Whatever you may be learning, if you regularly drop yourself into a time and place with nothing much to do besides the thing you wanna learn, then you'll do it more often.

Don't blow several hundred bucks on a ton of paints, or on pro software and a Wacom tablet. Just start with a few hardback sketchbooks and some pens and pencils. Oh, and not mechanical pencils. Just grab like a pack of Ticonderoga 2.5Bs, they're cheap and pretty good. And try holding them so that the side of the point addresses the paper for a lot of the beginning of your drawing; this will do several things for you:

* it will train you to keep your wrist fairly steady, and to draw more with your entire arm; keeping your wrist straight and steady will help keep the Carpal Tunnel Fairy away.
* it will make your initial lines light, and prone to fade away as your hand brushes the paper; this keeps you from bearing down to gouge an impossible-to-erase line in the paper, and gives you more room to make mistakes before having a dark, illegible mess of lines you can't draw over.

Don't get lost in trying to save a drawing, either. Paper's cheap, turn the page and try the same subject again, or a new one.

When you make a picture you like, hang it over your drawing board, turn it into your computer's backdrop, and keep trying to draw something better than it. You may find yourself hating it because you start seeing all the mistakes. That's great - go draw something new that doesn't make those! (This may take many tries, some mistakes are harder to stop making than others.)

Don't worry about "your style". If someone points out a mistake in your drawing and you find yourself wanting to say "but that's my style!", then you are just covering up your weaknesses unless you can actually sit down and bust out a version of the drawing that Does It Right. When you can do that you can legitimately say "dis mah style". Steal stylizations from artists you love (you're looking at other people's art, right? A lot?), make your own based on reality.

You will find a lot of people declaring "rules" of drawing. Always do this, never do that. The truth of the matter (IMHO) is that all rules of art are actually just warnings: "never do this" really means "if you do this without thinking about what you're doing it'll probably turn out badly". Know the rules, know which ones you're breaking, and break the fuck out of them while staying well within the boundaries of the other rules you know.
