For me, I find it helps by stepping away from the computer, taking a well-written book and reading it, and having a story provoke some thought about life and the world in general.
Everybody's work has some connection to another, don't stress over it. When you break fiction or something else down, you'll find a bunch of rehashed tropes. True creativity is a result of having experience with fiction, and combining a variety of your favorite works into something that personally appeals to you. You're on the right track right now, you just need to keep refining and learning.
If the storyboard doesn't work for you, trash it, take another gander at revisualizing the whole thing, and go through with a new storyboard that you feel works for you.
Yeah, you're right in that practice makes permanent, not perfect (I feel the former should be said more), but that's not a bad thing. It shows you care enough and have the passion and will to commit to quality in your work. Again. you have the right thinking here.
You don't know how to get better? Why then, Google some tutorials, scrutinize their quality, pick and choose what suits you best and mix 'em together to make your own style. Study from the best and from what you love. If you feel that you only love a limited range of things, try something different and find other things you never knew you loved before. Keep adding and adding to yourself and your craft.
Personally, for me, I go through sakugabooru and study the animations there frame by frame. I find it inspiring to see animations that were completely planned out by individual animators, and often I find new techniques and styles I've never seen before.
P.S. "Doing it right" often refers to learning the fundamentals before varying and experimenting. It's basically why art teachers stress realism before drawing cartoons; you need to know actual human anatomy before warping it for your own purposes. Fiction is an abstraction of reality after all.

If you look back in history, lots of artists struggle in the beginning, and then take breaks from their professions to do some soul searching. I think its part of being an artist :).
"I'm not a funny person, I want to have ideas and make funny animations and be original but I don't have the ability, skill or patience to do anything grande." Everyone is funny in their own way, since everyone has a sense of humor, stay true to yours and find the right crowd for it :).
I am not some sort of skilled artist, I am a trumpet and a sax player in a local jazz band. I do some improve and it tests my skills as an artist in its own way. Sometimes I feel like I am not making the sounds I want to, but the crowd loves it. Just like your animations, stay true to who you are, keep trying, and you will find the crowd that loves you. Remember big animations like "Family Guy" and "Futurama" were cancelled in the beginning because they were not well received, they changed their game plans and came back swinging.
So, all I can say is, never give up, stay true to yourself, and just keep swinging, you draw a lot better then i can :)

Thank you, that made so much sense it blew my mind. I guess I just have to look at things through the eyes of others and not through a harsh self critic. I'll try and keep this in mind. :)
