You can work and work and work and try and try and try, but there comes a point where you do have to throw up your hands with the knowledge that you can't solve all problems or please everyone. Doing well for others is a two-way street. Sometime you do give more and that's okay, but there comes a point, at other times, when you realize there's no winning in that situation and you put your energy elsewhere. There's no need for declarations, just a simple change in plans to do what you can where it matters and where it is embraced.
