I play lots of Free Cell, the solitaire game available on most computers. By lots I mean that since I discovered the game on my first computer in the mid 1980's, I have played thousands and thousands of games. Over all those years and all those games my winning percentage has remained constant. I win two out of three games on average. Sometimes I will have a winning streak, but it is always followed at some point by a losing streak. A 67% winner, that's me.
When I was doing my MSW clinical practicum, I spent many late night hours at the emergency room waiting. One of the main diversions of those late hours was playing free cell. My supervisor played as well. Once I asked him what his winning average was. He said in the 90's. I asked him how he did that. He said that he was a chess player and always played several moves ahead. I tried that strategy. I still averaged about 67%.
In life as in free cell some people seem to win 90% of the time, some 67% and some less. Free cell is like that. Life is like that. 67% is just fine with me.
