Alexandre, thanks for your thoughts! None of the things I mentioned are required, only suggested. Figure out what works best for you and apply it :) Here is another way of looking at it — Perhaps you don’t want to eat the same exact thing each day, so you choose to eat at the same restaurant but order different menu items. Doing that is a balance between being super strict and having zero routine at all. If you get tired or sick of part of the routine, you can always change it.
