why? are doers so rare

The world is made up of doers, do nothings and naysayers. The rarest are the doers. It is a gift. Do nothings abound. Perhaps it is not all their fault. They are caught up in the web of life; surrounded by the needs of family, work and self. Naysayers are the complainers. Most likely they are unhappy with their own existence. And they speak out, adding their misery to others. It is an awful weight they bring to bare on all of us. Ah, but thanks to the doers. Are they selfless or selfish. Interesting, but in reality it makes no difference. They are the ones who move humanity. Anyone can ignore or complain,but few do anything about it. How does the saying go "Never was so much owed to so few".
