“If you can’t be positive, then at least be quiet.”
If you think it can’t be done, then shut up so that people who are trying their best could do it. By the way you get no where by grumbling and complaining. At least be quiet just like the fishes in the aquarium. You don’t hear the fish complain do you? All you hear from them is “bubble, bubble, bubble.” A very powerful and a wise statement indeed. I like it better than your complaints.
