I was just looking for this subject. Basically I think there are 3 stages of destroying the mindset. The first stage is awareness. We must be aware of the mindset and its trciks. The easiest way to see them is to listen to inner talk. The second step is convincing. The mind needs something to believe in to move. So, just as you wrote it, we need to define a new way of thinking and organize our inner talk in a way that convinces the mind. The final stage is feeding. The mind has to be feeded to build a new habit of thinking new way. I thank you very much for writing and I have taken note of the steps you wrote. here is a nice video about mindset
