"Contrary to what we usually believe, moments like these, the best moments in our lives, are not the passive, receptive, relaxing times---although such experiences could be enjoyable, if we worked hard to attain them. The best moments usually occur when a person's mind or body is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile."

Although that makes perfect sense, I never even thought about this. I usually just do whatever's in my comfort zone and that gives me a sense of being happy and content, but honestly it's just that: a sense. It's not true happiness or contentment.

"The foremost reason that happiness is so hard to achieve is that the universe was not designed with the comfort of human beings in mind."

This is a very interesting observation. It's also true. What kind of universe would be "designed with the comfort of human beings in mind"? Is that even possible? In an alternate dimension, are human beings and animals happy all day, every day, regardless of the circumstances?
