This is a decision-making manual for adults who are done bullshitting themselves.

The Five Currencies of Life and the Happiness Equation introduces a practical framework for understanding what everyday decisions truly cost — not just financially, but emotionally, practically, and over time.

Drawing on lived experience, psychological insight, and clear reasoning, Ian Johnstone identifies five currencies that quietly govern every life: Money, Love, Knowledge, Ego, and Time.

Alongside these, the book offers clear, usable tools — including the Happiness Equation, the Pyramid of Triage the VIRTUOUS circles, and the P.A.U.S.E. method — to help you decide where your energy belongs, when something is worth the cost, and when it isn’t.
