Fortunately, much of what I do is just common sense, and anyone with some interest can learn to do it. Like a lot of common sense, though, it’s not necessarily obvious until after someone’s pointed it out to you.3 3 ...which is one reason why my consulting business is called Advanced Common Sense. “It’s not rocket surgery” is my corporate motto. I spend a lot of my time telling people things they already know, so don’t be surprised if you find yourself thinking “I knew that” a lot in the pages ahead.
