Perhaps, you should plan out your day in the mornings? I make a checklist of all the tasks I hope to complete along with a rough guideline of how long each task should take.
The French actually introduced 'decimal time' during the revolution with 10 hours in a day and 100 minutes in an hour. It was useful cos you could convert between seconds, minutes and hours much more easily
Time is just a concept, 60 minutes isn’t even real, it could be 100 minutes too but it wouldn’t make a difference. I don’t know if that makes sense but time is not a thing, it’s just made up of numbers we made
