I feel if you place importence on one aspect of the game, psychologicaly you are affirming that that is the area you must develop more than any other and therefore rely on the most.

We all understand that each day on the course is different, one day I might sink every putt in sight, others I can't drop anything outside two feet.

Ofcourse we must practice to keep these 'up and down' tendencies to a minimum but if you place importence and rely on one aspect, what happens when that aspect is not working for you? Your day may be shot because your game isn't complete (well rounded).

If you have placed no importence on any single aspect and one aspect does falter you have the rest of your game to rely on to steadily manoeuvre the course.
