The need to please destroys us and the people we are trying to please.
The only way to please all people all the time, is to override our own needs and priorities. We have to say no to ourselves to say yes to everyone else.
When we keep on saying no to ourselves we build up resentment and anger.
That will come out. Not immediately, and not even obviously.
But it will, and that will hurt the people we love more, than the temporary hurt of a "no".
