Opportunity cost is something that we aren't very good at applying to our experiences

THIS. I can't tell you how much I regret not giving Steem Monsters (aka Splinterlands) a chance back in the old Steem days. I had never played a battling card game before and thought I wouldn't enjoy it. It was only years later that I discovered I was wrong. I had missed the golden alpha, beta cards era, and half of the untamed era too. sob.
