Animators are made, not born. All of us are likely fail in most of the things that we do, at least at first. The key to success is to keep at it, and
fail faster.
Great animation doesn't emerge fully formed, it needs to be tweaked, revised and perfected. When you see a Pixar or Disney film, you see the finished, polished result - you don't see the pain the animator went through along the way.
Everything we do can be done better. If you don't keep trying, and practicing, and getting feedback, you will never create anything good. Your animation does not have to be perfect; you just have to get on with it and keep practicing your craft.
