I once spent an afternoon discovering I'm crap at Draughts. Lost about five games in a row. What I thought were good moves invariably turned out to be bad moves. I felt like my brain was incompatible with the requirements of the game, even though I understood all the rules. Very frustrating, haven't played since. But then it's a pretty basic game, not particularly exciting, am I really missing out by just leaving it behind? Nope. Sometimes it's fine to walk away and find better things to do.
