I remember learning about Kaizen when I was studying operations management, but somehow I never linked it back to 改善 which obviously is a term I know
One thing I tell myself I must do every new year is to go to bed earlier before 2am. I've been saying it for years. Last year, thanks to my dentist (long story) I gradually got it down to 1.30am. Occasionally, I manage 1.15am, and if I can get to 1am consistently, I'd be very happy as it has a knock on effect on the start of my next day.
