Ok, hold up. You don't have to animate the same concept/idea as someone else to become as good as them. I know how it is, i've been there myself. Practise makes perfect. And the most important thing is, be open for critisism. Learn from them. Everyone makes mistakes but you learn from it.
Find up some good ideas, find a target audience. Ask them what they want.
And last, but not least... Have fun making the animation
