In the workplace environment, I don’t think it is productive to dwell on what happened or keep score on who did what to whom. In English I would summarize my motto as:
Now I am looking for an appropriate Latin equivalent, i.e., a phrase that conveys:
- The past is behind me and does not matter too much.
- Today is a new day, and things are good. A non-defeatist point of view.
- We can accomplish great things by focusing on the future and not dwelling on the past.
I found similar discussion on another Latin site. Maybe it helps.
