How to apply From Strength to Strength: Finding Success, Happiness, and Deep Purpose in the Second Half of Life

Turn the ideas into something you can do this week.

Audit your first-curve chase

Name one status goal that still owns more attention than it deserves.

Schedule a wisdom transfer

Offer one concrete lesson, template, or introduction to someone earlier in the path.

Invest in one relationship

Put one non-transactional call, meal, or walk on the calendar this week.

Reduce one applause metric

Stop checking one ranking, count, or comparison for seven days.

Write your second-curve sentence

Complete: 'In this season, I want to be useful by...'

Practice subtraction

Remove one obligation that belongs to an older identity.

Mentor without performing

Ask someone where they are stuck and listen before giving advice.

Protect a quiet hour

Use one hour for reflection, prayer, reading, or deep conversation.

Define enough

Write the conditions under which today can count as enough.

The second curve begins when success stops being the scoreboard and becomes something you can give away.
