Wealth is not a number or a comparison to others. It is having enough money to support a life you have already defined. Because the target is set by your own definition rather than by relative standing, a person can be rich without being wealthy, and wealthy without being rich.
Most financial advice starts with portfolio tactics and skips the question of what the money is for. Without a defined picture of a good life, no amount of optimisation can tell you whether you have enough. So the target keeps receding and accumulation becomes endless.
People adapt quickly to gains in income and possessions, so each gain delivers a short lift before satisfaction returns to baseline. Pursuing happiness through more stuff is therefore a treadmill. Lasting satisfaction comes from experiences, relationships, autonomy and mastery, which resist adaptation.
Markets, returns and the economy are outside an individual's control. Savings rate, costs, diversification and behaviour are inside it. Financial effort should focus on the controllable few, and attempts to predict or outsmart the uncontrollable should be treated as a source of error.
Good investing needs no complex strategy. It follows a few durable rules: diversify, keep costs low, stay the course, and accept the discomfort of volatility as the price of returns. The biggest threat to results is the investor's own emotional reaction to losses and to other people's gains.
