How to Break through limiting Beliefs? ie Poor Mentality?

[Matt Rathburn]

Hi everyone, I've recently identified that one of the major things holding me back from breaking through is a poor mindset. I suspect I have a subconscious limiting belief that I either don't deserve massive wealth or I am unable to get it. I will say I've read Rich Dad Poor Dad like 30 times and I understand there is a difference in the way poor and rich people live. If you were to look at my life most people would say I'm successful. Gorgeous wife, successful real estate business, nice home, etc. The problem is I'm not where I thought I would be at this point in my life. Has anyone broken through this type of belief and transitioned from moderately successful to massive wealth? If so, how did you do it? Affirmations, meditation, visualization, hanging out with successful people, attending a Tony Robbins seminar, NLP, there's so many things, is the answer to try all of them? Just wondering what has worked for people.
