Inability to understand people.

Even though I know quite a bit of psychology at times I become vulnerable to human emotions. I have misunderstood people before. The most devastating of all is that often I have chosen wrong people in lieu of right people!

I am too bad at choosing and ever regretted that. Human heart you know…ever irrational.
