Only way to make something better is to change it. Thats a fact and it will be always that. It doesn't matter wether you are changing the matter itself or something linked to it, but aslong you change something only then things can turn better. Offcourse it's a fact that changing can be bad thing too, but all you have to do is change it again and again until it turns out like you want it. Thats one of the problems of this century too little change and everything is staying still. Usually the bad way still. If you are afraid of change then you should think is the way that thing is ok with you or not? If it isn't ok then what do you have to lose? Embrace change instead of avoiding it. Remember that you can always change to something else until it turns out good.
