We live in a digital age and don’t often need to communicate via paper and pen. That means we cherish a handwritten note in which the person offers their thanks, condolences or congratulations. We save the notes at our desks or file them in a special drawer. We don’t throw them out.

If you want to leave an impression in the business world, then buy a pack of thank-you notes, a roll of stamps and locate a pen in blue or black ink. Then send handwritten notes when the moment requires one. That’s the mark of a true leader.
