I think it's way easier to keep in the flow than to start things and this delays my sleep rythm too if I'm not forced to get up in the morning. (I'm still a late person and will max out flex time at work to only get in at 10am or something) 30min downtime after work however is nothing, that's not warmup, that is well deserved rest and while meditating sounds super healthy and mahjong doesn't I'd argue it's quite similar. I think your brain needs this, especially if you do mental work during the day. But even on a free schedule I'd say off-time keeps me sharp. If you took hours on a saturday I'd recommend habits: read hn (or what ever you choose, just not all of it) in bed so you than have a clear cut by getting up. Than have some pleasure along with starting your todo: good coffe and a nice sandwich or something. Another trick is keeping your todos tiny: find a tiny thing you can do right now without it feeling a burden and don't feel pressured to do more. Once doing it it's often easy to continue by free will or at least have the task working in your brain in the background to get you back to it later.
