Dr Mike Israetel is a Professor of Exercise and Sport Science at Lehman College and the Co-Founder of Renaissance Periodization.
How do you boost motivation and actually follow through on the things you know you should do, but don’t feel like doing? The answer isn’t more stimulants, thankfully, it’s something far more grounded in neuroscience and behaviour. Today, Dr Mike Israetel breaks down the science of willpower in a way that works for the average person and can even help make your daily life much more productive.
Expect to learn the science behind willpower, habits & motivation, the de facto two kinds of things you should be doing with your time, how to know when its time to do things you actually feel like doing versus making yourself do things you don’t feel like doing, how to integrate habits that improve your life and get rid of the ones that don’t serve you, how to improve your willpower, how to become more antifragile and build your resilience, and much more...
