I notice that when I focus more, altruistically, on others, I am happier. For instance, a friend is going overseas for the first time. I am really excited for him and I hope he has a blast.
'Meaning' is a tricky term. You have the obvious things like spending precious time with loved one, making sure they are feeling all right, followed by things like gratitude for what large and small things we have in life. It takes real effort to do this sometimes.
