Is it unhealthy to overanalyse everything in life and take life very seriously?

You decide: I think you've answered your own question. If you try to understand everything about yourself or other people, you'll fail -- people are born different and have only a limited ability to be who they want to be, let alone who you want them to be. Relationships are more important then being right; a job u enjoy & a few good friends is all most of us need. Understanding this made my own life easier.
