I've read "Six Pillars of Self Esteem", and listened to the audio book, and I found it very revelatory. I really liked it. It's very useful if you already enjoy living, but not of much use if you find life to be endless drudgery. The ideas in the book were helpful for my self esteem, no doubt. But that's not really my problem. My problem is just that there's nothing in life worth the pain of living it. and I can't even envisage any life that would be worth living.
I've gone about my business and found it to be drag. That was the question. Let's say you follow the logic and agree with it, you set about achieving life, and you find the whole affair utterly miserable.
It's not a matter of permitting, it just is that way. Perhaps you have such power over your own mind but I don't. My emotions are not within my direct control. If they were, there would be no problem. Why would I want to feel miserable all the time? That makes no sense. I know not how to control my own mind that way. Perhaps you can explain it.
