When you have developed a certain degree of drawing skill, it might be a good idea to start joining an art community. The reason for this is mainly for motivation purpose. Countless artists give up while in the learning process and it's because they ran out of motivation to keep them going. In many country, artist is a rare specimen, and they usually grow in the 'normal' environment. Being different from the others usually causes one of these two bad result; you are either praised by your friends and family and tricked into thinking you're already the best at what you're doing, or instead your friends won't even care how great your talent are and makes you think your skill is so useless and insignificant.
You are the product of your surroundings after all. If you only live in your own small world you won't be able to see the big picture. You might be thinking that you're the best now, none of your friends can draw better than you. Well, that's a fact. I'm not saying you're just imagining things. You ARE the best, but only if compared to your little neighbourhood. It's the same case when you think you're so insignificant, that your skills are useless because none of your friends or family appreciate it. But that might NOT be the case out there! You might be surprised to find out that you're already at a great level and there's so many people that admires your skill and might even pays you for what you did everyday!
