If I would measure my daily succeess based on my habits and the rate I'm able to keep doing it I did fail hard yesterday. I Skipped 3 out of 4 habits that I am focusing and tracking.
But that doesn't actually bother me. It's ok to skip them every now and then. What matters more is getting back on track. Skipping shouldn't become a habit. Then I would have failed.
Today I'll continue as usual, do them all again. And then tomorrow and so on. A new streak, new achievement to head towards. I don't even intent to do more today to catch up, there is no need for that.
Some time ago I was thinking of starting to write down the reasons if I would skip any of my habits, but now I don't even feel that it would be necessary. Not at least unless there are going to be a lot of them in the future.
