How am I actually meant to celebrate Friday Hour Done?

I did Monday Hour One for the first time last week. I made it through with not too much negotiation (I called it optimization on the fly 🙂 but my Friday Hour Done fell really flat. I just felt spent and exhausted.

I did get a lot of stuff done, and I scheduled downtime and early nights, but how can I do better this week? Is there something specific I can do to ‘celebrate’ better so I don’t get discouraged and stop doing it?
