An experience pays out twice: once when it happens, and again every time you remember it or retell it. The earlier in life it happens, the more years those returns build up. So an experience bought at 25 can be worth more over a lifetime than the same experience bought at 65, even if the price is the same.
Divide your life into five- or ten-year periods and assign each experience you want to the period when you can best do it. Health, energy and circumstances open and close the window for many activities, like backpacking, contact sports or travelling with young children. Deferring them to retirement often means you lose them rather than delay them.
Money helps a recipient most when they are roughly 26 to 35, when it can fund a home, education or a business. An inheritance typically arrives when the heir is around 60 and already established, so its marginal value is low. Giving to children and charities while you are alive both improves the gift's impact and lets you see its effects.
Money is stored life energy: each dollar earned cost hours of work. Anyone who dies with a large balance traded irreplaceable time for purchasing power they never used. The book counts over-saving as a real loss, not a harmless surplus of caution.
Your ability to convert money into enjoyment declines with age as health and mobility fade. So your spending curve should front-load experiences rather than hold spending flat or let it rise as balances grow. Past a certain point, extra money cannot buy the experiences your body can no longer have.
