What could you accomplish if instead of complaining you either took action or kept your mouth shut?
Complaining is easy. Everyone complains, either out loud or to themselves; and there is an infinite number of things in our world about which to complain. We feel compelled to tell the world when we’re aggrieved, but to what end? To be heard? To bully until your needs are met? To feel like you matter? You already matter, that’s a given, so it’s a silly point to argue.
What if you eliminated the urge to complain? What if you made deliberate choices and decided that something was important enough that you would work on resolving it yourself or with likeminded people? Or, in the grand scheme of things, you decided that this particular matter was trivial to you, and not something you needed to fight for, or against. You may not like it, but you’re not willing to invest the effort to address it yourself. You can endure it. You can keep your mouth closed, not complain, and forego your dismaying gesticulations and groans of disapproval.
This is not easy, especially if you are a chronic complainer, and you find yourself surrounded by a chorus of nitpickers and fault finders. Try anyway. Go an hour, a morning, a day, a week, finding things to praise. Should you come across something that is not to your liking, see what you can do to fix it or find an alternative. Pick your battles instead of defaulting to blame and irksome accusations. Develop a bias toward action.
