Dear Jason,
thanks for this post. Based on my own experience, the first stage of overcoming the behavioral biases is just to be aware of them and consistently study behavioral finance literature. Over the years you will begin noticing the biases within your own behavior and behavior of others. Then you are ready to correct the biased decision-making by applying the advice documented in the vast behavioral finance body of knowlegde. But it just takes time, a lot of time...and you never completely win over your innate characteristics still.
Best,
Michal
