Changing your lifestyle is more about how our brain works, how we learn, and our behaviors than it is about the workout, the diet, or any of the specifics. That’s not to say that the specifics don’t have importance as they are the executables that ultimately represent the change.
One of the keys to making learning and change stick is the concept of interference.
As we learning new behaviors (or anything for that matter) it seems that the more we do something the faster we learn it. Repetition is a key element to behavior change and learning, but evidence shows that if we interrupt pure repetition of one concept with learning something else at the same time, we learn both concepts better.
As you work your way through ALL GAIN, NO PAIN, you can enhance learning the principles by reading something else too. I’m usually reading 2-3 books at the same time. (currently reading Cell, Gels, and the Engines of Life, Game Changer, and The Undoing Project)
To help others out, what books have you found valuable in regard to supporting behavior change? Learning? Attitude? Pain? Exercise?
Here’s a few off the top of my head:
The Obstacle is the Way
Explain Pain
The Upside of Stress
Why Zebras Don’t Get Ulcers (my favorite book)
The Willpower Instinct
Ego is the Enemy
Oh, and don’t forget fun stuff too:
The Dark Knight Returns 
😎
What book would you give to someone as a gift to impact their life, attitude, or for fun?
