Drawing comes from a firey passion deep within one's soul. It doesn't appear just one day out of the blue, it is something that you have to build, just like a love relationship.
Drawing is expression, there is no right way to draw, too many people think that realistic proportions are the only way to go, but, most of the time, this limits the creativity of a person. In other words, if abstract is the way to go for one, then fully go for it.
Practice makes you perfect, if you really have any intentions of drawing, you will need to practice a lot knowing that improvement can be, most of the time, years away. But looking back can also encourage you as well.
