6-Action

It's all part of the plan

6-Action is a directory for actionable headings.

"People should be nicer to each other" is not actionable (by you). "Be nicer to people" is actionable.

A dissertation on why people should be nice to each other goes in 7-Background (or perhaps 3-Names if you'd rather file it by author. Or both, with a link.)

Your 12-step plan to start treating people better goes under 6-Action.

These actionables won't show up in Org agenda. This is a good place for headings you're considering doing, or have deferred. Or for ongoing projects that generate specific actionable headings for Org agenda, and thus would be redundant to include in Org agenda.
