Do you or have you ever read Mark Sisson's blog, Mark's Daily Apple; or his book, The Primal Blueprint? He's an excellent read. It's thanks to him that I've become comfortable and confident with making the best food choices I can but not sweating the small stuff. I can't afford all organic and grass-fed and pasture-raised foods so there's a spectrum of priorities that I follow.

I think I got it from something he wrote, and it's a paraphrase, that I should aim for excellence, not perfection. I incorporate a lot of his recommendations and principles in my way of eating and way of life and do the best I can.
