Know your purpose
A clear reason to get up in the morning — the Okinawans call it ikigai, the Nicoyans plan de vida. It is a felt sense that you are needed and that your days matter.

Why it works
A strong sense of purpose is linked to lower stress hormones, better sleep and more engaged, active days — all of which compound into healthier ageing.
What the evidence says
Research cited by Blue Zones associates a strong sense of purpose with added years of life expectancy versus those who report none.

How to apply it
- Name, in one sentence, who or what needs you right now.
- Build one daily activity around that purpose — a skill you're growing, a person you help.
- Revisit it at each life stage; purpose shifts as roles change.
