It's hard to make / find a routine for me too! I can have a perfect routine for morning and evening but in the middle, when I'm working, it's always winging it. š
I have written so many routines over the years but I find it hard to keep up with them as life gives many changes all the time.
I have done something following current routine I made for myself in Google calendar, but it's a small part of it. š
I guess my biggest takeaway is that you need to be realistic how much you can do in the given time + preparing and planning also takes time and it should be part of the routine. Also - a very good strategy is to have themed days - Mondays are computer work, Tuesdays are meeting clients etc. What fits your to do list!
All the best!
