I think it was Netflix's mantra, "If it moves, measure it".
And another company I worked with lived by "If you do it once, document it. If you do it twice, automate it."
I like both of those.
I'd like to propose another saying to take to heart - "Live in your logs."
So often logs are things that we look to only when there is trouble.
As a concrete example, you may find users engaging with a feature that you thought was not being used, or the opposite. Maybe you've put a lot of time into something and nobody is using it.
Log what you care about and look at it. Every day. Insight comes from seeing the patterns over time.
