Thoughts about life

How can I find out what limiting thoughts about life I have to know what exact thoughts are holding me back from living the life or achieving the goals I want? To give an example just in one area, financial, I believe that it can be easy for others to make millions of dollars, but not for me. I don’t like that thought, but at least I am aware of it. What about other limiting thoughts that I am not aware of and manifesting in my life? How can I eliminate them?
