> Exhortation to develop those good habits in the good times, I suppose.

This is what medication for more severe cases of things like depression is supposed to offer: an opportunity to learn, usually through therapy, to cope with the condition in a healthy way.

Yup!

Same thing for ADHD.

Medication helps having willpower/focus to develop better habits and realize you are not a useless dumb human. It's just that your brain is a little finicky to get going sometimes.

In fact the few diagnosed ADHD people I know are wicked smart. It's just that their brain overclocks to unproductive levels without medication.
