From a very early age my wife and I told our son that there are times and places for everything. I told him look when you're in class you have to be quiet and listen to your teacher but when you go out to the playground you can scream and be silly.
Early success is a terrible teacher. You're essentially being rewarded for a lack of preparation, so when you find yourself in a situation where you must prepare, you can't do it. You don't know how.
