Although it won’t often earn you the big bucks, artistic skills are highly desired because they provide you with the technical abilities required to create something beautiful. You’re going to have to find your own inspiration and subject matter, but the skill you’ll need is really just a matter of technical aptitude and practice.
Picking up a book of anatomy and drawing different bones and muscles will teach you how to draw people. Drawing grids over photographs can show you basic perspective. Obviously it isn’t as simple as that, but focusing on learning to draw one simple thing, like the petals of a flower or the human hand, will help you learn how it works and get in a reasonable amount of practice. When you’re ready to move on from the basics and start illustrating on your computer, check out some digital painting lessons. Those of you interested in photography can find lessons for that, too.
Whatever you’re looking to learn, just set aside 15-30 minutes every day to practice a very small part of that skill. It’ll take a while to teach yourself how to draw, paint, take better photos, make hamburger sculptures out of clay, or whatever it is you want to do, but breaking the daunting task into pieces and practicing each part slowly will help get you there. Plus, it’s a really nice way to unwind at the end of the day.
