In our digital age, I mailed 30 handwritten thank-you notes last month. The responses stunned me - 3 recipients cried, 15 called to thank me personally. Neuroscience shows handwriting activates the gratitude centers more deeply than typing (University of Indiana research). My template: 1) Specific detail 2) How it impacted you 3) Warm closing. Try it with your barista or mail carrier!
