This metaphor fits so well, when you consider that making changes in your life never involves throwing out the whole; They involve small things, improvements to who you already are. It's particularly apt, though, when those changes involve actually physically applying a patch to yourself. You'll never be perfect. You'll probably have to apply patches forever.
Step 26: Realize that nothing is perfect, and the moving toward the change you want will require continued effort, even if it never quite gets you there.
