don't know. whether my self-esteem is high or low, but it started to bother me by my fairly mature years. It's usually a problem for teenagers who are still getting to know themselves, or for young people with family problems. And then, I, who had been quite successful in life, started to worry about self-esteem. The thing is, I had a good education, worked hard and was respected as a professional. In the last few years, I've been pissed off by people treating me as incompetent at something elementary when I meet them. For example, young people, looking at me, as it seems to me, think, "Well, he is not young anymore, he doesn't know anything about new technologies". I get angry when in a conversation I am asked idiotic elementary questions about programming, computer programs, thinking that I am a complete fool. And every time I have to "prove" it. I don't know why this has become a problem for me. I say to myself, "Well, tell them at once that you have done projects on programming, speak at scientific conferences on innovations. And then I object to myself "why so stupidly assert yourself". and I silently listen to the next stupid questions of "boys": "well, you know how to register e-mail". Oh, yes, I do, baby. I think I have a problem, because a normal person does not need to prove anything to anyone.
