You could argue about right- versus left-brained people, and say that you're just more in tune with the left hemisphere of your brain, but a quick Google search brings up numerous reports about the myth of right- versus left-brain. While the two hemispheres do have unique properties, they share information so much that we as a species use both equally. (here's a link to just one article from Psychology Today). You can even see how silly your argument sounds when you look at a famous artist/inventor: Leonardo da Vinci. Are you going to argue that the Renaissance Man himself was predisposed to be better at art because he was more right-brained? But what about all of the mathematics that went into his inventions? He was talented because he worked hard to be talented. Take a look at that study of the bones in the arm. That is called a "study" for a reason, and da Vinci did hundreds of them. These studies are the key to his talent.
A New Definition of Talent
You need to listen your internal desire to improve and shut out any negative thoughts. Yes, your art will look like a child's when you first start, but just like a child, your creative ability will grow if you correctly foster it. Talent is practice.
If Practicing is the Key, How Often Should You Draw?
Let's take a look at another number I only recently heard, this one from a much more pop-culture source. You'll probably laugh, but the cool thing about art is that you are always learning, and knowledge doesn't always come from sources you expect. This tip comes from animator Ross O'Donovan (aka RubberNinja) on an episode of Game Grumps. (for those of you left scratching your head, Game Grumps is a comedy gaming channel on YouTube). In an episode featuring Ross drawing Pokemon, he mentioned that he kept reading how artists should strive to fill up a sketchbook a month. Thankfully, Ross does the math for us this time, continuing on to say how a sketchbook a month comes out to be about only four sketches a day. While this number is a lot more than each of my professors required, it's still very reasonable. Keep in mind, these are sketches and practice, not fully rendered pieces!
My personal routine is to try to finish a rather large piece a week and then at least a sketch a day. I work on commissions most of the day during the week, then in the evenings doodle whatever silly thing I want. I'm usually sketching for fun while my other half and I watch whatever TV series we're hooked on that week. Even though completing a large art piece a week might not be feasible, you still need to push yourself to try. I highly suggest drawing while doing other things like watching TV! It definitely helps make some boring studies fun.
Other artists will suggest a doing certain number of hours of drawing a day, or doing even more sketches than Ross's four, but the question of how often you should draw really boils down to "as much as possible". The more you draw, the faster your talents will progress. Aim for that sketchbook a month. Make art your priority. I know it seems like a lot of work, and that's because art IS hard work. You have to practice everyday; you have to push yourself. But just like that silly workout motivational poster above, all that hard work is worth it. know it seems like this blog turned into a rant about practice, but that's because I don't believe in any innate talent. Hard work, dedication, and your drive to improve are what make you talented. You are talented. You just need to put in the effort to unlock it!
