My biggest flaw in meatspace is that I am too friendly, trusting and kind.
It is a set of behaviours I have tried very hard to cultivate in myself. I think the end of the process has only now just started to bear fruit: A lot of people just want to use me for what they can get out of me. I get too close to people who end up hurting me, despite their overtures about how they are good people.
Many people close to me warned me about this about myself. It was hard to understand what to do until I got burned a few too many times. It’s like anything in learning, I guess: you can be studious in a classroom, but you only learn until you get to practically apply what you have been merely told.
