I love that book. I think the premise is to give up activities that don't really add much value so that you can focus on what means the most to your business, like long term growth.

Finds ways to ditch responding to email, accounting, advertising, and other menial, routine chores so you can be engaged with actively growing your business and developing your team.

I think it's about getting back 10 hours you would have spent on menial chores and spending five to eight more hours on really purposeful stuff. In the end, the menial stuff gets done by others, you spend more time on truly impactful activities, and you might get some extra FREE time out of it, too!
