> Saving 4 minutes a day on a process, over the course of your lifetime you will save 1200 hours. That’s a half year of vacation.

If I had to micromanage my personal life that way, I'd need a lot more than half a year of extra vacation in my lifetime to stay sane.

I value not having to think too hard about running my personal life higher than saving a few minutes here and there. Let alone wondering if those saved minutes are really fungible enough to translate into bulk time or money savings elsewhere.
