The importance of routine
I think people have the misconception that having a routine limits people to live life most vividly because it restricts their daily lives, but I slightly disagree.
Yes, setting a routine theoretically removes some degrees of freedom from someone's life by definition, but I'd argue that it frees up so much more bandwidth and energy to put into things that actually interests the person.
We spend a lot of unnecessary energy thinking about what to eat, what time to workout, what time to wake up, when to go to sleep, etc. And all of this variation clogs up people's mental clarity.
But when having an established routine, all of those questions are already answered and executed without thought, freeing up energy to be used on other, more important ideas or tasks.
