Is it possible to talk about another person without talking about yourself?

I can imagine others’ feelings at times. I can imagine why they act the way they do. I can make judgements on people’s characters, and I can imagine that I know how they can right themselves. But I cannot enter their body and soul and actually know what’s behind the action that I see from my own perspective. In and instant, I make assumptions about the causality of others’ actions that in reality trace back to the moment they were born.
All I know is myself. It’s all I’ve ever known. In fact, it’s all I’ve ever had access to. I can make educated gusses on the causality of things in other people’s lives, but it’s always going to be short sighted. I’m not a business man, so if I see a guy in business lose money on an investment, can I really make any judegment at all on him as a business man? If I judge him and say that he’s a bad business man, aren’t I really saying that if I were in the same position and makes the same mistake that I would judge myself as a bad business man? That same failure can end up making him all the better, or he could have falied on purpose for all I know.
Talking with certain about anyone but myself is certainly the same as talking about myself. It’s unavoidable.
When I say that the world would be a better place if everyone smiled more, exercized more, had an artistic outlet, and led a spiritual lifestlye, I’m really just saying what would make me happier. Judgeing others is only a way to avoid listening and reacting to myself, the only thing I can ever be sure of.
