Hi. I wanted to do the working for 40 days but forgot and did it on the 41st day today. I should have stopped yesterday. What would you advise? Is my only option to keep going until 80 days?
You hit 40 days, anyway. The permanence is there, regardless if you did it for an extra day. In my opinion, you completed a full cycle and can stop, unless you want to go to 80.
