It's pretty simple. If you need to do something more than once a month, it's time to automate that.
It may be obvious to automate things that you need to do daily or even hourly... but it's those once or twice a month things that are really crucial.
Those are the things you'll most likely forget to do, then play catch-up or ignore all together until you're in trouble.
Homework: identify what it is that you keep postponing, forgetting to do or outright ignore. Then ask yourself: "HOW MUCH WILL I BENEFIT FROM HAVING THIS THING DONE ON ITS OWN?"
Then... simply automate it.
I'll teach you how. :)
