Is this really free?
Of course the answer is a resounding NO. While what we are doing may have no monetary cost, it certainly has an opportunity cost. (For anyone not aware, opportunity cost is the cost of doing one thing while you could be doing something else.) And bad choices can make opportunity costs terribly expensive.
One analogy I often use is my $100,000 chair. That was one of the most comfortable chairs I ever had and I spent many happy hours sitting in it in front of my computer ... before I gave it away. The opportunity cost of sitting in that chair was at least $100,000.
With that in mind, how do you decide how to spend your limited time on your business? And did opportunity cost play any part in what business you decided to go into?
