I have a theory on when to work through anger and when to channel it.
When you’re not sure of the source of the anger, it requires working out. Without clarity, it will compound and damage things around you. A tangled ball of causes will accrete complexity unless you stop and start to unwind it.
When you know exactly what you’re angry about and you can isolate your focus to it without dragging in anything else, it’s probably a good time to channel that into some kind of productive activity.
First, understand it. It often dissipates from this alone, or drives you to conversations or actions that do. If it doesn’t, channel it.
