How do you split out your time daily?
Do you have a repeatable daily schedule or do you approach every day as something new? Do you spend your morning doing important tasks or do you prefer to do them in the afternoon? How much sleep are you getting? Do you feel you should be getting more or less?
I like to have a routine day to day, but it's hard getting into a routine. I don't sleep much. ~5hours/day. I should sleep more but I like to get up early, get some exercise in, sort out the important emails and prioritise calendar tasks for the day. Ideally, I'll do the tasks that require significant thought early on in the day and do less cerebral work later on as I lose energy, but that doesn't always happen.
