Many people I have met have a painful habit: grumbling.
They grumble about the state of things around them. They grumble about how the world appears to be against them. They end up making enemies of persons who could have been friends. And then they grumble even more!
Their situation reminds me of a story I read a few years ago. That of a dog sitting on a nail, and yelping in pain. When another dog asked him about his plight, he said it was because he was sitting on a nail.
The other dog then asked why he was not moving away from the nail. He replied, "It's not painful enough!"
The people who grumble too have a choice like the dog. They can do something about the things that make them grumble.
When something irks you enough, it is better to take action than just talk about it. The world around you can be a better place if you are willing to make the effort.
