I often catch myself going down the rabbit hole, skimming one Wikipedia article... then suddenly it's two hours later and I have ten tabs open about a crazy assortment of subjects.
The Free Dictionary provides the following definition but doesn't offer its antonym.
go down the rabbit hole
To enter into a situation or begin a process or journey that is particularly strange, problematic, difficult, complex, or chaotic, especially one that becomes increasingly so as it develops or unfolds. (An allusion to Alice's Adventures in Wonderland by Lewis Carroll.)
Question: What's the opposite of that?
Staying focused, keeping on track, skimming, just addressing the obvious?
