Your business improving is about what you need to do, not what you elect to do each day. You do what you do because you want to do it, rather than learn what could or should be done to get better and get out of your comfort zone and risk looking like an amateur.
Of course doing what we want to do each day is one benefit of owning our own business, but it’s not likely the way to grow it.
The leader is responsible for all of it. Is your business the way you want it? Is it because you don’t know how to lead it any different, or because you won’t?
