Anything worth doing, is worth doing badly at first.
Being an animation student, one book I read was Chuck Amuck: The Life and Times of an Animated Cartoonist by Chuck Jones, a pioneer animator and director of the old Looney Tunes cartoons so many of us know and love. A story from that book made a deep impression on me, and even though I dont remember it exactly, I want to share the gist of it with you.
When he was starting out, Chuck was told by a senior animator that everyone has about 10,000 (I dont remember the exact number here) lousy drawings in them they need to get rid of, before they can really start drawing.
According to Chuck he used that line to spur him onwards, sometimes drawing and re-drawing his work again and again just so he could get that one perfect drawing.
Whenever you do something new, you will most likely suck at it, or even fall flat on your face. Be prepared for it, its natural. Finding something difficult can be a sign that youre learning something new, if its too easy its probably has elements of what you already know.
