Action by action -- Every time I do some little thing that matters to me with diligent attention, it's a win because it will be easier to choose it the next day.
Create a routine -- Even before I retired, I planned what my routine would be. The week before our first lockdown, I planned my routine. I never dreamed it would be so long before we could approach normal life again. Having outside events give structure to my life again will be pure luxury!
Get one small win each day -- I aim for three: my prayer time, my treadmill walk, and writing something. Like the old song: "Two Out of Three Ain't Bad".
