Actually a baby has to crawl before it learns to walk. You know how to walk, you've just been preferring crawling because you're so used to being happy with the crumbs you are given by your wife and those crumbs and sprinkled gingerly on the ground, hence the requirement for crawling. If you had high standards for yourself, you wouldn't settle for crumbs, you'd let her be for a while, you'd focus on you and get your $hit together and stop trying to impress a wife who's been having affairs and giving your herpes - something to think about.
When you settle for less, expect to get less. When you stop settling and only expect the best, expect the best things to start happening in your life.
