Most book summaries give you bullet points you forget by lunch. Book Knowledge gives you one idea, one real-life example of it in action and a ten-minute exercise, three mornings a week.
The idea. Seneca's claim is that we don't have too little time; we waste a lot of it, mostly by letting other people spend it for us. We guard our money and give away our hours without noticing.
What it looks like on a Tuesday. Maya, a product manager, counted one week of her calendar. 31 hours of meetings; she'd chosen 9 of them. Nobody stole her time. She'd accepted every invite by default, the way you'd leave a tap running.
Try this today (10 minutes). Open tomorrow's calendar. For each meeting, ask: would I pay $50 of my own money to attend this? Decline or shorten one that fails. Put the reclaimed hour on the calendar as a named block, or someone else will take it.
The one-line version. Treat your hours like your money: count them, and spend them on purpose.
Each issue covers one idea from one book, with an original real-life example and a 10-minute exercise. We quote briefly and link the book; we never reproduce it.
