Have you tried just visualizing or feeling what you’re grateful for vs. writing it down? Which one worked better and why?

Before I write down I remember what happened in my day that I am grateful for and feel how different actions or people made me feel. After I feel and remind myself of this I choose the ones I think were the most important ones or the ones in a bad day I would love to look back to and I write them down. In this way I appreciate everything thst happened during the day and save some memories for the tough days I don't seem to remember anything good in my life.
