David made me realize how weak our society today is and how important it is for us, entrepreneurs, to get stronger and keep toughening up. People get offended for no reason, worry about insignificant sh*t, lose their composure when something irritates them a little, or give up just because they faced a tiny obstacle.
If you get good at suffering and pushing through despite immense pain, insurmountable obstacles, and unfairness, then everyday problems won't bother you at all. On the other end of the spectrum, if you stay in your comfort zone, protected from everything that might be unpleasant, then even the tiniest problem will feel like the end of the world.
One of the things I realized thanks to the book is that I'm not pushing myself even 10% as much as I should when it comes to physical fitness, which is one of the best ways to toughen up not only physically, but also mentally. I consider myself fairly fit, but what David does is on another, incomprehensible level. I'm going to change my routine and raise my standards. Time to take some souls.
