Here is an excerpt from this Zapier article. I found curious that I never took time to think about the differences between these words.
Habits vs. Routines vs. Rituals: Wondering what the difference is between habits, routines, and rituals? Habits are things that we do automatically–things like checking your email first thing in the morning or putting your keys in a specific spot when you get home. Routines are usually a collection of habits or actions you do on a regular basis to bring order to your day–checking your email, then writing your day’s to-do list, then checking your team’s project management tool as a way of getting the day started. Rituals are like routines. The main difference is the attitude behind the actions: Taking a walk everyday at lunch could be considered a routine if you think of it as something you need to do for your productivity. Or it could be a ritual if you think of it as a way to break out of the mundane and enjoy nature. While we’re focusing on habits and routines here, most routines could be turned into rituals with a change of perspective.
