Seth Godin wrote a blog post a while back called "The Illusion of Control." You can read the whole post here. The gist is that we need to come to grips with the reality that we actually have no control over the outcomes of our actions. In fact, all we are in control of are the actions themselves. We can only influence the outcomes.
This is particularly frustrating for successful business owners who are scaling their organizations. Making the change from doing everything to merely influencing everything is difficult. Some can’t cross that bridge ever, and hopefully can be at peace with whatever size business they can manage to sustain by being a "genius with a thousand helpers."
