How do you express gratitude? via /r/gratitude

There will be moments in my life where I feel an overwhelming sense of love and gratitude for the life I’m living and the people who are living this life with me. I am constantly experiencing anticipated nostalgia – a term used to describe missing a moment before it has even passed, because I know that in the future, I’ll look back on this time so fondly.

Sometimes I feel frustrated that I can’t express my gratitude in a way that matches how big and full it feels. So I’m curious – how do you express gratitude?
