I’ve been living the same way for around size weeks now. Most mornings, it’s up by 4:30. Then working out until 6:30, followed by going to work.
You notice breaks in the routine, once it’s created. Any deviations seems off, and it can unbalance the day.
However, you also have to be prepared to pivot. Being unbending is a sure way to crack under pressure.
