This is such an important principle to me that I've spent a lot of effort developing tooling and mental models to help with. Biggest catalyst? Being on-call and being woken up at 3am when you're still waking up... in that state, you really( don't want things to go slowly. You just want to fix the damn thing and get back to sleep.

For example, looking up command flags within man pages is slooooow and becomes agonizingly frustrating when you're waking up and people are waiting for you so that they can also go back to sleep. But if you've spent the time to learn those flags beforehand, you'll be able to get back to sleep sooner.
