People are different

I often say to my friends that I've only recently realized that people are different. I've always thought that everyone thinks in the same way than I do. That everyone has the same values. That good is good for everyone and bad is bad for everyone. How wrong. What I just wrote may seem funny and obvious, but I've also realized I'm by far not the only person with this beliefs.

Things are changing now, but there are still traces in these beliefs in me. I should interact with other people as much as possible to learn more, understand relationships and, what's most important, myself.
