How much damage can $3 do to someone who makes some hundreds of dollars per month? I can only feel the pain if the amount I almost successfully grabbed is very big.
Same thoughts. The pain is there when we're almost going to grab that pot and then we didn't. That $3 won't be a huge damage for us because we can always take that back. A meal that will cost $3 is what we have to sacrifice then we're again back to that amount. While that potentially big grab of pot, it's hard to get back on that position when we think that it's going to be different the next time we bet and start with that amount.
But if we keep losing $3 like for 10 times, that's another story to tell and we should feel the pain also with that.
