Draw a tiny image of something (like a hand), on the same page over and over again from top left to bottom right.

By the time you've made it to the bottom right. You would've filtered out the kinks and smoothed out the edges. Now take a clean sheet of paper and draw that last image again, and this time throw in some shading... repeat the process, but add on more layers (Scaling, coloring, mirror images, etc) each time.

Tldr version: Practice on thing until you've mastered it before attempting to draw anything else you're not comfortably familiar with.
