I get through a lot because I get up early and I take advantage of my energy, which is at maximum in the mornings. I usually never do too much but a bit every day adds up. I have my stop time and that is always by 12 and my reward is a treat after my lunch and is mostly a couple of chocolate brazils
I would say that a starting point could be to know your own circadian rhythm and then go with the flow, so make a short list and do one thing a day, if you have the energy.
Personally I have what could be a wasted time, at the end of the day, before I go to sleep at 10. I go upstairs at 8.30 after making sure that the kitchen looks nice for the morning. I get ready for bed and then go into my sewing room, which has a completely different ambience to the living room. Then I sew for a short time and bit by bit over time, I get a garment made
