I know everyone says "exercise" yada yada... I always avoided it because well I'm skinny and felt the time would be better used working. Wrong. There is simply no replacement for what exercise does for the brain. For the last week I've been getting up, drinking a full glass of water, and then running 1+ miles. Results? I've finished more work in 1 week than all last month, at least I feel that way. I notice my brain no longer gets "hung up" on silly problems that a 5 yr SEO such as myself should not be worried about. I also have been thinking of strategies and testing things I hadn't even considered over the past few months since Penguin. So if you don't currently exercise, DO IT... I promise you it will directly impact your business in a positive way.
