When it’s time to be grateful,do you write it down,say it in prayer or do you just say what you are grateful for out loud?

I try to make my gratitude list everyday. My friends and I also have a habit of sharing our "highlights of the day". It is much easier to be positive if we remember the good things not only bad (that are quickly stuck in our heads), at least for me. I also list some things I’m grateful for when praying, but in this case in life in general.
