You might look into having more of a daily time budget, rather than an actual routine.
When thinking of managing the time in your day, you could make a schedule, routine, or just a time budget. There is no rgiht or wrong method. The goal is simply to accomplish what you need to in a day.
Schedule - tasks done at a specified time each day; little flexibility
Routine - tasks done in a certian order, but not at a specified time; more flexibility
Time Budget - tasks done within a specified time limit (no more; no less); flexibility in structure, but not in length of time spent on any given thing.
