The Gap and the Gain — Book Notes

The author opens with a mental map:

Start → Achievement → Ideal

• Start is where you were at some point in the past.
• Achievement is what you've actually accomplished since then.
• Ideal is where you wish you were.

Focus on the distance between Start and Achievement — and you feel successful, satisfied, confident.

Focus only on the gap between Ideal and Achievement — and you feel like a failure, deflated.

The author calls the first orientation the Gain mindset and the second the Gap mindset.

Consciously reminding yourself which lens you're currently looking through is what gives you the chance to pull yourself out.

Looking at the book as a whole, the author's focus is on making it easier for people to feel happy and satisfied. The observation is that the same situation looks entirely different depending on your perspective — and because the brain is forgetful and loss-averse (losses feel larger than equivalent gains), the book presents this reframe as a practice: notice, shift, internalize, habituate.
