Have you ever had a home repair problem arise, so you decided to pick up something to fix it? Did you go to the store and buy a few items that you hoped would solve the issue? Then, when you get home and start to work at the repair, you start to notice other problems arising. You succeed in overcoming some of them; however, that one special tool that you specifically bought for the first problem gets put to the side and forgotten about.
You get back to your original task and wonder what you were going to do about it, while that solution sits waiting in anticipation.
