I definitely agree with your view on "It's Okay To Be Wrong!" Most people are worried about making mistakes as well admitting to them. However, I have usually learned a lot more from my mistakes compared to when I have gotten things right.

I also really like your water bottle example under "Stop Believing in Willpower." Your suggestion there actually matches the concept of a nudge. It's something that's suppose to alter how you behave without banning or forcing to you to do something. As you stated before, willpower is limited. It's a resource that drains over time so it's best to find easier ways to achieve our goals.
