You can’t even say it’s an information problem. I constantly do the wrong thing even though I know many people or a particular person thinks it’s a bad idea. Because I don’t have their conviction in its wrongness.
One way I started facing some of my problems was just to ask other people how they fixed theirs. Sometimes I liked to just hear stories of people fixing problems I have never had. (like quitting smoking) I heard stories ranging from "My boss said he'd pay for my seminar fees if I joined him at this anti-smoking retreat. And my husband copied everything I brought home from that, and we both quit smoking together." The husband said the thing that helped him was to go through the routine (or rite) of smoking, but without the cigarettes. He'd go outside, stand there for a bit, pretend to open a pack, pretend to smoke one, taking deep breaths. And then go back inside.
Who would think to do that on their own? Another guy I worked with said "I quit because my wife asked me to." There was a deeper story there, but he was a man of few words. None the less, he noted why another guy couldn't quit smoking in our work place. "Jim, he will never quit. Notice how when he tries to quit, all he says to himself is 'Man I really want a cigarette', he won't quit."
There are all kinds of subtle clues to human nature, and your/mine thought processes hidden in discussions like this. Watching some people fail and some people succeed. I found that with all the things I faced, that if I keep looking, and don't quit, I always find an answer to my problem that I can actually do. The conviction comes from my belief that it's possible and this gives me encouragement to act.
