Late nights, long hours.It’s 10:00PM and I’m just wrapping up a class on technology marketing for a group of engineers made up of folks from Intel, Synopsis, and Tektronix. They look tired, but they’re tracking the material, studying hard, and putting in what it takes in these late nights, long hours.They know education, these folks. There are eight of them in class and not only do they have their bachelor’s degrees in computer science and master’s degrees in engineering, they’re here studying marketing with me as part of their MBA regimen. And still, in spite of the years they’ve put into their academic careers, this is hard work.
