I draw often and I find it enjoyable. It's a passion and a hobby for me. I don't think I'm particularly talented at it, but I've been drawing for years. As someone else mentioned, pick up that "Drawing on the Right Side of the Brain" book. I highly recommend it as it'll give you some good starting points. You can also download some e-books by Andrew Loomis for free. I know a lot of online resources too, if you're interested.
Other than that, the best thing you can do if you want to improve your drawing skills would be to draw often and draw from life. By life, I mean, setting up objects or people in front of you. Don't try to just draw from photographs or from imagination. Also, focus on realism, at least when you're trying to learn. Don't immediately try to draw cartoons. Doodling is fun, but you'll see little to no improvement this way. You need to know what something looks like before you effectively stylize it.
