Mental game

One of the most difficult parts of the golf game is the "mental game." Many professionals have special trainers to robust their psico in adverse circunstances. When they fail one par, they recover in the next one. It's what is called the "bounce back". Most of the professionls have a high pourcentage of bounce back.
On the contrary, all the golf amateur players suffer of a opposite illness: when they superseed their expectations in one hole usually they fail the follow one. It is well known the expression "after a birdie, a shit". That is the result of lack of mental game, one aspect that the professional trainers don't teach the amateurs to robust. A amateur must keep always his expections in a low level, if possible ignoring what they have just done in the previous shot. They must do a kind of game "shot by shot", always trying to do the best way they can and they know.

Another aspect the professionals are very strong is to play with public and many of them the more public they have the best they play. They were trained to do so. For them golf is a show game.
With the amateurs it is also the opposite. Some, even if they have just one person watching, they feel the legs shaking and fail the shot. So, golf amateurs have to adopt one attitude very simple: ignore everything around, the other players, the assistants, all.
