Let's be real: There is no bigger waste of time than running a booth at an industry trade show. When you think about it, all the time it takes to find an appropriate event, prepare for it, travel to it, set up for it, and begin talking with potential customers, you would have exhausted way more time and effort than necessary. Not only is it a waste of time, it is a waste of money and the cost typically outweighs the return from any leads you may accquire.
