XKCD

Jeff Smith: If it saves you a little time, many times over the course of a day, it quickly adds up. XKCD says that if you're using a particular thing for five years, then if you only shave off one second each time you run it and you run it five times a day, then you can't invest up to two hours in flash command line. But there's another aspect as well. And that's the aspect of implicit documentation by condensing this build deploy and execute thing into one step. That also speaks to other items on this list, like test driven development.
