Two things I always hated were intentional networking and constantly keeping up on industry news. They both felt like homework that took up off-the-clock time. That is, until I adopted this method.
Every time I would fly I would pick up a few copies of an industry magazine (the more recent the better). While most people skip over the first 10 pages of ads and the Table of Contents, I would scour them – for the Notes to the Editor section. I would read these notes, making sure I knew the articles they were referencing (or would quickly find and read them), and then would jump over to LinkedIn. Anyone who had an interesting take or comment got an invite request. Did everyone accept? Of course not. But enough managers, directors, and CXO’s did that it was always worth my time.
