Stoicism talks about some of this too. It's amazing what happens when we start realizing that everything in life that happens, happens for our greater good. For our fulfillment or education. Now I know some really bad shit happens some times and it's not explainable, but I think living the way you described still applies. I posted about stoicism a few days ago and there's a link included that takes you to a free ebook by Tim Ferriss who wrote a great book about stoicism. I'll post here if you don't mind.
