3. Tom Clancy said it best: “Life is about learning; when you stop learning, you die.”
In a world of rapid change, you can probably see his point. If we stopped learning within the last few years, we wouldn’t know how to talk to Siri or how to access Hulu for TV shows we’d like to catch up on. We wouldn’t be able to keep up with fashion or the latest in gastronomic delights. Our perspectives, tolerance, world views and understanding would not have been broadened. For me, personally, not learning would mean I would have missed out on traveling abroad and on discovering a mad passion for Sudoku puzzles.
Like it or not, we are learning all the time. We have to be just in order to keep up with everything that’s happening around us. Even so, many adults resist formal learning. They do not choose to attend training courses offered by their employers and, if forced to attend, exhibit an unwillingness to really open up and try new methodologies. Going back to school for degree completion programs or advanced degrees is tantamount, for some, to going to prison. Reading a book, attending a lecture, watching a documentary film, sitting through an online tutorial or any other on-purpose learning activities seem highly undesirable to many.
