It seems that a big reason why some of us are so unhappy with their lives is that we always think that the fate hasn't been so kind to us as it has been to someone else. We tend to envy our neighbors for having more money than us, a bigger house than us, a hotter spouse than us and so forth. Why is it so difficult to be content with what you have? Why do we always want to have it as good as someone else has? And finally, how to get over the feelings of envy? What to do so that you never feel bad when you see someone else making something, that you're reduced to dreaming of, a reality? How to feel content regardless of what you have and what fate has given you?
