I have been told that there is someone who is blocking me to get where I need to and I feel that I am stuck in on place. What should I do now??

The devil is in the details so please share them. Otherwise no one can have a clue as to what you are talking about.

I don't what you mean. You been told, who told you? Anyway, if anybody is in the way of your personal growth, its you. Most of the time it take will to go ahead.
