You can keep keep a journal and that's already probably too much information. Who goes back and reads that stuff? What is the point of logging every step you ever too when it doesn't matter in the slightest? I keep track of some details in regards to exercise, but I throw the sheets away at the end. And the values I keep are just to reference how much I am doing and if I should increment. Is there really anything interesting about going back to check on that? Does a big long Apple Watch streak equal a life lived?
