No, there is nothing stopping you from trying. Only those telling you that "you are weak, it is impossible, don't waste time, you need help all the time because you can't do anything on your own, don't bother because we know better than you," those are the people trying to stop you.

And if you believed them, then no matter what genes you have you would have failed. A person with 20/20 vision can be fooled into buying glasses, a young beauty can be taught that makeup is still essential, a person of sound mind and healthy body can be convinced that he cannot run.
