Imagine your toy sales went down, but more kids played with each toy longer; that's good news, right?
Some numbers are super important; check those every day! Other numbers? Look at them once a week or month.
If lots of bad things happen together – like fewer sales AND less playtime – then you need to look closely!
Sometimes, a small problem isn't important; it's like a small boo-boo. Other times, a big problem needs fixing right away!
