I find myself strongly disagreeing with the "world view" behind this post - though the common sensical statement "don't go with defaults all the time" is great, the post exudes an ego-centrical way of viewing life - make choices based on what you think will make YOU happy.
The "killer quote" that pushed me over the edge to post this was: "It could be a major change, like getting rid of your spouse" .... seriously? "Til death do us part...or I feel like you're not making me happy"?
I do not believe true joy is found in selectively surrounding myself with people that make me happy and "eliminating" all others. In fact, to act as if true joy is "just around the corner" if we would simply make the right changes like learning how to surf is a dangerous illusion to give.
