I'm an idiot, ha, ha, and I'm glad I'm. Ever since I started reading, I've been doomed to become an idiot for being captivated. You speak frankly about your own experience, and of course, it is tempting to try to be inspired and wish I could do the same. I have attempted parts of your program and, as you say, didn't follow through; sooner or later, I gave up. Not exactly a diet, but a healthy diet and a much-needed sleep discipline, because I had apnea, which seems to be the cause of some heart problems (arrhythmias). I am over 71 years old, and, as you say, time is becoming increasingly valuable. Therefore, I spend my nights trying to gain more time, although I know it is an illusion. Too much about me, this post is about you.
I am amazed by your perseverance and discipline; I have never met anyone like you. I think you will succeed in everything you set out to do, but I wonder, because you have to give up so much, is it worth it? I'm asking myself, not you. You know where you want to go, and if you get there, the answer is simple. It was worth it.
