Recently came across another blogger's post called "The Secret of Happiness". Basically the idea is
"You are much happier when you assume that everyone likes you."
I used to live like this up to about 7th-8th grade. I easily made friends with everyone, and truly felt there was nothing wrong with me when it came to interactions with other people. Then some unfortunate social events gradually changed me to someone that assumes everyone doesn't like me. There are pros and cons to both attitudes, but I think it's obvious that I've been rarely happy since the change.
Ignorance can truly be bliss. Living in a world where I genuinely believed everyone liked me created some haters, but I dismissively shrugged them off and stayed with those who loved me. When I discovered that I wasn't hot shit, I felt incredibly naive and stupid, and began a much more careful and apprehensive approach to social situations.
While this attitude was great in keeping good terms with everybody around me, I was never secure or happy with myself as a person. Unnatural behavior took over, and I've always felt a little awkward since. Today, I feel I must be perfect, or live unhappy/lonely forever. It's a lot of unhappiness, but at the same time, I guess I enjoy it in a twisted, be-the-best-that-you-can-be way.
