I usually do because it helps me keep track. I like the records to be accurate so that I can focus on the challenging part.
I used to. But it doesn’t do anything for me except make the record number go up. I figured I might as well focus on wholeheartedly doing my routines in the present day. I know what routines I did and didn’t do, and logging them ultimately doesn’t make me any more or less accountable to them. I just acknowledge that I forgot to fill out a day and I keep it pushing.
