But that most of my day is taken up with worry. With brooding about the past. Or fixating on the immediate future. With wondering why I did or said a particular thing. Or trying to figure out how I will survive and prosper.
Happiness is of the moment.
You can smile at thoughts of the past. You can be glad about something coming. You have to be in the moment. Which has been exceedingly hard for me. As much as I'd like to live as if the future is now, as though the past doesn't matter, it's a real struggle.
