Discipline and distraction are definitely a thing when it comes on focusing upon what needs to be done. I often have to shake my head and stay focused because distractions are either everywhere around me, or I am wired to chase squirrels.

The inner monologue thing is a POWERFUL concept when you take control of it. The older you get, the better you get at not wasting time and spending it on the stuff that helps produce results or enjoyment.

Hopefully that is ;)
