When we have been hungry for a while and we finally eat, it can take time for our appetite to subside. We may have to consciously decide that we have had enough, even though it doesn't yet feel that way. A similar challenge can arise when we are wrestling with a problem. We find the solution; we apply it yet it can take time before we see definite evidence that this has had the desired result. Meanwhile, we carry on worrying, even though there is no longer a need, don't restart something that you have already finished.Challenge?
