True enough. There is no way for any company to please all of the people all of the time. So you just have to get used to the idea that even though you are doing your best you are going to disappoint some no matter what.
I remember when I first really understood that it was actually cathartic. It enabled me to go forward without feeling bad that the whole world was not happy about something I did.
So while I empathize I no longer agonize!
