The obsession with wanting things to turn out a certain way is in itself unhealthy. Life is much more interesting and rewarding if you follow a non-deterministic model. It's a journey with no goal and it's really really short. I've been much happier and achieved a lot more when I stopped hoping for outcomes and started enjoying the moment, the here and now. Life is what is happening right here right now, or as John Lennon (actually quoting Allen Saunders) eloquently put it, "Life is what happens to you while you are busy making other plans".
