Problems, like rabbits, multiply if left
Other people's problems if left will often go away as they will solve them, but your problems if left will usually multiply. So if you should do something, it is better to do it sooner rather than later, lest it grow. Would you rather deal with a few rabbits or a plague? A little acorn root that can be pulled out with one hand becomes a tree that needs a chainsaw. Unless someone else is giving you food, washing your clothes and wiping your bottom, don't ignore the problems you see. Ignoring a thing doesn't mean it will ignore you. Nothing in nature stays still - so problems left alone grow. As misery breeds misery, so problems create problems. If you see something you should do, then do it directly, lest its progeny overwhelm you.
