“What you’re supposed to do when you don’t like a thing is change it. If you can’t change it, change the way you think about it. Don’t complain.”
Maya Angelou
Why exert effort on an immovable object? I think this applies to complaining about things that you can’t change. In fact, complaining as a rule is a waste of effort and energy. I can’t think of one time in life where I have felt better for having complained without then taking some action to create change. Complaints because you just have to be heard don’t result in change. So why bother?
