> Automation not only saves you time, it changes what you do.

This bears repeating. When you automate a task, you often push it over a "breakpoint" where it suddenly makes certain things profitable in terms of effort. For example, say you fill up a water bottle and place it within arm's reach, instead of running to the tap every time you're thirsty. You save maybe 10 seconds per sip, but the real win is that you can now consider behaviors like "drink water every 5 minutes" that previously you would have considered too much effort.
