What are you focused on? What you have or what you don't have? Regrets, problems, mistakes, resentments, things in the past? Cant' change it. Are you focused on the future? This causes worry/anxiety. What you can change is what you focused on. Are you focused on the now?? What you have, what you're grateful for, small to big goals, learning something, growing in some way, contributing to others in some way??
