I'm developing the concept of memento gratias. Akin to memento mori, but for gratitude and awe. One of them is water fasting when exercising. Then, getting back home, drinking a large glass of cold water slowly, and being mindful that such a thing (safe, cold, on-demand water) was out of reach for pretty much every single one of my ancestors, but thankfully, I get to enjoy it. We live in a world of abundance. Let's make the world better, but let's not forget about the progress we've made.
Here is a good sample of those things we tend to take for granted: https://ordinaryabundance.com
