Your brain is an amazing instrument that can help you live a richly varied, exciting life. A lot of people think that, if they just control what they know and ignore what they don’t, they’ll limit any possible discomfort and be happy. They even do it to others.
When you cut off the flow of information to your brain it begins atrophying, like a muscle that’s not being used. On the other hand, if you constantly use your brain to learn new things and become more knowledgeable, you become stronger and have more information to effectively deal with the challenges that come your way. The world becomes less scary and you become more confident when you release the power of your brain.
