Make a date with yourself to journal every day. I try to journal in the morning when the house is still quiet. You don’t have to journal about something that is earth shattering every day, it can be about the fact that this is Saturday and you got up early because the cat would not let you sleep in.
My Dad journaled almost every day. He started out by writing down the temperature and if it was windy, or if there was rain, which is a big event here in Arizona, but he started. He may have gone on from there about something else. But the point is he journaled every day.
You will be surprised when you start how satisfying this is. Journal, open your heart.
