Here is my example. There is this girl that I know likes me, and I called her house about 20 minutes ago. I know she was playing hard to get, but I still worried about it. I'm worried because when she picked up, she said "why in the world are you calling my house?" I said "why does it matter?" and she paused for a minute then said "alright, bye". She didn't hang up until I said "hello?" a minute later, though. I'm worried that I could have said something better to make her like me even more (I'm a perfectionist, so I'm always looking into the hindsight of things un-voluntarily). The feeling that I got was basically "yeah, I could have done better, but I'll have to wait until next time or next call to make it better" and I felt really good about that thought. For the few seconds that it stayed in me. The feeling went away one second later and now I'm stuck here, still worrying that I could have done something better for a better immediate result. In other words, I'm thinking "what could it have been like if I said this?" all the time. So do you guys feel like this (at least some times?) and how can I get rid of this worrying hindsight? If anyone can help me out, I know it's you guys.
