It's part of our nature to want approval from others. If we weren't so busy entertaining ourselves to death, we would realize that we also want to deserve the approval. What we really long for is to be respected, and to have self-respect. Unfortunately, we settle for the cheaper self-esteem.
The problem with self-esteem is that it requires feeling special and above average. Of course it's impossible for everyone to actually be special and above average, so we develop what is known as 'Self-Enhancement Bias', which is the tendency to think of ourselves as superior to others. Studies have shown that our youth think of themselves as better than others; smarter, funnier, kinder, more friendly and trustworthy, for example. But unfortunately, their opinions of themselves are not based on actual deeds.
