Handwriting is unique. It’s personal. It’s individual to you. It communicates more than just the words and ink. It communicates your humanity in ways that type never could.
A reply I wrote to someone who asked why I even further might advocate journaling by hand versus typing and printing.
Don’t think of your journaling being solely for you. Think of it being for those you leave behind. Which would they rather have? Which will they be more likely to cherish and keep?
