I dubbed 2014 as the "Year of the Handwritten Note".
Sending notes shows you care. In a world of easy digital communication the effort of putting pen to paper will allow you to stand out from the crowd. Physical notes make people feel good. Share that feeling!
The US Postal Service is raising rates on January 26, 2014 (up to 49 cents for a first class letter). My advice is to stock up on the "Forever Stamps" now (at 46 cents) and then start using them (each letter will feel like a bargain).
Have A Great Day
