There is this TV ad of (two wheeler or car or something?) where one women complains how people throw garbage on the road and how dirty the place around is, while throwing a used cover on the road. The second women just walks and picks garbage and throws in the dustbin. This is how our habits work. We complain before looking at our own actions.
Give us the serenity to accept the things which cannot be changed, have courage to change the things which we can and the wisdom to know the difference.
