Drawing, like many skills, require a great deal of patience. No one on this planet is born being able to draw, there are those with natural talents but even then that took years to achieve.
If you have a sketchbook, carry it with you. It's a simple trick used by just all artists at some point. I never leave home without my convenient pocket-sized sketchbook. Take it to a park, a rock concert, anyplace there are people and things that are interesting. Fill up dozens of sketchbooks, and keep them for reference.
Though drawing from life won't help you with thechniques such as layout or costume and character design, it will give you a solid foundation of anatomy, one of the most important aspects of drawing.
