The trouble with facelifts is that there's always extra effort involved. Either by the writer, or the contractor, or the writer/ web-designer/ stay-home-dad, or the surgeon. Energy needs to be expended in order for said things to change. They're not going to magically transform without that extra effort.
So the question becomes: is it worth it? Maybe, if you've been rejected countless times by numerous publishing houses, or water is starting seep in from the roof, or your website looks like something a grade 7er could build, or you're middle-aged and have more wrinkles than a catchers glove.
But who says you have to change? Who says you'll be "better" after the change? Who cares? Don't change - it's too hard, and probably more effort than actually required.
Nothing ventured, nothing gained... You'll never know, I guess.
