Changing the world is like trying to straighten a dog's tail. However much you may try, you won't succeed. But although the tail won't straighten, if you keep trying every day, at least you will put on some muscle. Similarly, even though it is difficult to make a change, our effort to do so in itself brings positive results. It will help us change. Without waiting for others to change,if we change ourselves first, that will make a difference. Instead of worrying about results, focus on doing our best in what we are engaged in.
