If anyone is struggling with sleep, I highly recommend episode 1-3 of the Huberman Lab podcast ( [VIDEO] ), it has literally changed my life. Dr. Huberman is a Neurobiologist at Stanford and explains the science of sleep vs just telling you to not look at bright screens at night. I struggled with sleeping for 20+ years, now I easily wake up early. The biggest game changer: Sunlight in your eyes within 30 minutes of waking up. Try morning walks for 1 week (without sunglasses) and your life will be changed.

Check out Dr. Andrew Huberman's podcast #1 on YT. "How Your Nervous System Works & Changes" He argues that feeling overwhelmed and the frustration of learning are necessary to activate the neuro-chemical processes needed to change our programming. Interpreting this emotional state as "doubt" is itself a mental program that can be changed when you realize that these neuro-chemical processess are necessary and normal. Also, get good sleep (which he covers too). [VIDEO]

I probably learned that fact from an episode of neuroscientist Andrew Huberman's podcast, and it is more likely than not that I learned it from episode one: [VIDEO]
