Something important is that if a person is healthy and has bread and water, he has the whole world with him.
What is this world other than a healthy body, peace of mind, bread, water, and a garment to wear? Why don’t you and I use math to calculate what we have and what we don’t have? I think that most of us will find that we have more than 80% of the things that make life comfortable. Needless to say there are exceptional cases when one is deprived of important necessities, but for the most part, we weep over comforts that are missing without laughing and being thankful for those that we do have. We are sorrowful when afflicted, and ungrateful when all is well.
