Throughout my life, people have looked negatively on routine. Routine wasn't "cool." What was my response to this? Well, of course, I tried to be spontaneous as possible and tried to be a "roll with the punches" kind of person. What did this get me? Frankly, a lot of anxiety. I underperformed in several aspects of my life because I was worried about being judged for meeting my own needs. As an adult now and a more vocal advocate for all things to do with mental health, I can safely and proudly say that I function much better with as much routine and consistency as possible. Routine can help anxiety and disorganized minds so much. If you can anticipate what is going on around you, you're less likely to end up in a high-stress situation. This is not to say you should try to schedule every minute of your day because that's unrealistic and setting yourself up for disappointment and discouragement. However, taking daily tasks you know you have and putting them into a time frame for the day can help greatly and help you plan the rest of your day.
For example, my almost daily morning routine consists of:
Run the dishwasher
Feed my toddler
Sweep
Mop
and then I generally take a short break to decide what else needs to be done for the day.
My evening routine is:
Cook dinner
Feed the kids
Give medicines
Put the kids to bed
