If I had to explain this quote in my own words, I would simply say something such as: Don't take any of your things for granted. When you actually take the time, and think about what you have, that other don't have, it makes you appreciate you and your surroundings. The simplest material items, that we don't always recognize, such things like a pair of socks, we tend to just pass by, because we are used to having such things. We don't see the real worth, when such a thing as thing could greatly benifit thousands of others. So if anyone tends to get upset about not having what is wanted, think about a lot of the others out ther, who don't have what is needed. Be happy for what you have.
