I, too, owned it for about 5 minutes. Happy to see it doing well, though.
It's not the things I sold too early or too late that bother me, for some reason. Sure, it would have been great to get out of CYDY at $10.00 or to still be owning this. Or SE.
It's the decisions not to buy something that bother me. And maybe they weren't wrong. I know I put my money somewhere else when I looked at and decided not to grab MSFT at $45-$50 back in like 2015. And maybe that worked out OK after all. But it annoys me that I made the decision not to buy it. Or when I looked at LULU in '17 and after an earnings pop said, "Nah, $70 is too expensive. I'll wait for it to pull back." Dumb###.
