Two key points, one of them similar to 168 Hours (Amazon) – which I also really liked. We all get 24 hours in the day. Your time budget is that 24 hours, minus necessary things like sleeping, eating etc. Whatever is left is what you have to work with. You need to be strategic about what you put in it. What are your priorities? Work, relationships, exercise, etc.
The other point I really liked was about layering, which is about fitting more in. This is combining things that use different channels – like listening to podcasts whilst walking, or talking on the phone whilst cleaning. This is what I do when I combine my workouts with watching TV.
For me this book was a <30 minute read. Well worth fitting into my time budget!
