The Defining Decade

Three of the ideas you’ll keep

The Clif summary of The Defining Decade pulls out 7 insights. Here are the first three.

1. Don't waste the decade that matters most: roughly 80% of life's defining moments happen by age 35, and small decisions in your twenties compound like a plane shifting course a few degrees at takeoff, the gap between landing in Alaska or Fiji.
2. Collect identity capital, not just paychecks: take the job, project, or experience that builds the most skills, credibility, and relationships, even over the one that pays slightly more right now.
3. Use your weak ties, not just your inner circle: most real opportunities arrive through acquaintances and friends-of-friends, so make yourself interesting, do your homework, and ask people just outside your tribe for help.

The other 4 — and the full 10-minute summary — are in the app.
