Do you get in your own way?

I recently came across this article and love the concept.: How to get what you want. The idea is simple enough but so often asking for what we want is such a hard thing to do. Why is that? Why is it hard to ask? Is it the question? Is it identifying what we actually want? Is it shame or concern over what others will think? What do you think?
Check out this article and let me know what you think.
