Rituals are not routines. A routine is something you do to get through the day. A ritual is something you do to remind yourself you are in it.
Mine are small. Coffee in the chipped blue cup. A walk at four in the afternoon, whatever the weather. Ten minutes of reading before bed, always on paper.
Anchors
On hard days these little anchors are what keep me from being swept along. However the day goes, I know there will be the cup and the walk and the book.
You probably already have rituals. It is worth noticing them, and protecting them.
