I'VE worked in many places and done many different types of work all around the world in my 46 years of living, including being a boss and working for bosses.
I get the whole concept about the business stuff that matters, like strategies, systems, processes, products and plans. But where we so often fall short is the people stuff; this is the stuff that really matters. The best business strategy will produce the worst result if it is led by people who are not valued or respected.
Smart bosses take care of their people who take care of their business. It's simple but in very short supply.
Some stuff about me: I've been self-employed on and off for the majority of my working life. I left school at 16 to pursue a sporting path moving into professional playing and coaching offshore at the age of 20. So for the past 26 years I have been learning how to motivate, encourage, lead, mentor, survive, connect and listen to people of all shapes and sizes. And while I run my own consultancy business nowadays I'm less of a boss and more of a mentor/leader.
In my years of experience many of the bosses I have encountered are brilliant at the brainy, theory, intellectual stuff and very poor at the people stuff - which means they will never be very good at business.
