Perfect for you if...

- You're building a business or pursuing ambitious goals and suspect better sleep could be your competitive edge.
Maybe not for you if...
- You're looking for deep scientific theory rather than actionable tactics you can implement this week.
- You have a diagnosed sleep disorder that requires medical intervention, not lifestyle tweaks.
- You're sceptical that something as simple as sleep could meaningfully improve your health, fitness, and productivity.
