10-10-10 Rule

The 10-10-10 framework was introduced by journalist and author Suzy Welch in her 2009 book of the same name as a general decision-making tool for both professional and personal situations. In personal finance, it was adopted as a practical antidote to impulse purchases and short-termism — the cognitive bias that causes individuals to overweight immediate gratification relative to long-term consequences.

The first question — 'How will I feel in 10 minutes?' — acknowledged the immediate emotional pull of a potential purchase or financial decision. A flash sale notification, a desire to upgrade a smartphone, or an invitation to join a speculative stock tip group all generated an immediate response that tended to override deliberate judgment. Asking this question allowed the individual to name the emotion (excitement, fear of missing out, social pressure) without immediately acting on it.

The second question — 'How will I feel in 10 months?' — introduced medium-term perspective. Would the new laptop still feel exciting, or would it have become just another device used for the same tasks the old one managed? Would the equity position taken on a friend's tip still seem like a sound decision after the market had moved, or would it register as a poorly researched gamble? Ten months was long enough for the novelty of most purchases to fade entirely, yet short enough that the financial consequence was still recent and tangible.

The third question — 'How will I feel in 10 years?' — anchored the decision in the frame most relevant to wealth building. A Rs 2 lakh vacation taken on credit in the 30s, financed at 18 percent personal loan rates, represented not just the direct cost and interest but also the foregone compounding of Rs 2 lakh invested in equity over a decade. Conversely, a decision to delay a significant home renovation to preserve investment capital might look trivially inconvenient in 10 minutes but entirely rational in 10 years.

In the Indian personal finance context, the 10-10-10 rule had particular relevance for several recurring decision types: whether to withdraw PF early for a non-emergency purchase, whether to take a personal loan for a wedding expenditure beyond one's means, whether to break a long-running SIP during a market downturn due to short-term anxiety, and whether to invest in a market-linked real estate project at a phase of the cycle that felt exciting but might look frothy in a decade.

The framework was not prescriptive about what the right answer was for any given question. Instead, it functioned as a metacognitive tool — prompting the individual to examine a decision from multiple temporal vantage points rather than from the single high-urgency vantage point of the present moment. Used consistently, it reduced the frequency of financial decisions driven primarily by emotion and increased the proportion driven by deliberate, multi-horizon reasoning.
