WHAT'S STOPPING YOU?
That is usually a layered question. If you really want to do something but you just can't seem to get yourself there, ask, "What's stopping me?" Write down the first thing that comes into you head. Then ask it again. Write, Again, Write. Again, Write. Continue until you can't think of another reason. I'm betting I know what the final answer will be.
Ultimately, the only thing that's keeping you from your dreams is you. Once you are willing to accept responsibility for that, you can begin to change your thoughts and change your life.
