Three don'ts to be happy

There are so many ways to become happy and healthy. Some of them are easy to allow, some are not. But still there exists a so-called life copybook maxim that is worth paying attention to. It includes three don'ts - don't worry, don't hurry, don't carry. Superficially it seems to be silly and too easy, but if to deepen your perception and comprehension you'll understand they are main in keeping fit and healthy. Think it over.
