Read “who moved my cheese” - be grateful for the cheese you now have. But giving thanks to who took away the old cheese forcing you to move on? Nope, mice that move on don’t do that.

Zen story: two monks walking a path come across a woman stuck trying to cross a stream, one of the monks carry her over and they continue their journey. Shortly the other monk asks “I am troubled brother, we are prohibited from touching a woman, why did you do that?”, the other monk replies “I put her down by the river, for me that is in the past, but for you, you are still carrying her”.
