I might agree that buying new clubs every year will not improve your game. If it makes you feel good about yourself, and if you can afford it, then by all means - indulge.
Lessons, on the other hand, not so much. I really question if the money spent on lessons by a mature golfer is going to help him/her to improve. Most will go back to their natural swing soon after. Once that happens he/she will start thinking about another lesson - and round and round we go.
