Mastery is one of my favourite topics because it teaches you why the best way to achieve success is to commit to the effort required not the specific goal. That is counter intuitive but every bit of experience and research supports this simple vision.
This interview with Andrew Huberman an American neuroscientist and associate professor in the Department of Neurobiology at the Stanford University School of Medicine. He explains in a beautifully simple and practical way how to use the natural chemicals in your brain such as epinephrine and dopamine in a more positive way to develop better habits to achieve success.
This research links closely to the growth mindset work by Carol Dweck.
