Can you audit your own life?

Accounting has always been more than arithmetic. At its core, it is a way of thinking: deciding where limited resources should go, weighing trade-offs, making judgements under uncertainty and understanding long-term value.

The interesting question is whether those same principles work outside the office, too. After all, most finance professionals spend their days allocating resources that never appear on a balance sheet, such as time, attention and energy.

What's important?

Start with materiality. In accounting, materiality determines whether information is significant enough to influence a decision. Not every number deserves equal attention; what matters is whether leaving it out changes the bigger picture.

Many things in life feel important simply because they arrive loudly. A delayed reply or a forgotten birthday message can seem significant in the moment, even when it does little to alter the broader direction of things. A useful question is: will this still matter six months from now?

The point is not to dismiss small things, but to avoid giving everything the same weight. Otherwise, genuinely important things risk getting buried in the noise.

What's being neglected?

Then there is depreciation. Few assets hold their value forever. Time, use and neglect all leave a mark, which is why accountants spread a loss in value over an asset’s useful life rather than treating it as a one-off event.

Missing one morning walk rarely changes anything. Skipping one catch-up with a friend is unlikely to damage a relationship. But small decisions accumulate. A missed workout can turn into weeks without exercise. One postponed catch-up becomes a friendship maintained mostly through birthday wishes. Neglect is rarely obvious until the cost has already been paid.

What's missing?

Another accounting principle is opportunity cost, the hidden trade-off behind every yes. The price of a decision is often not what it gives us, but what it leaves behind. This blind spot even has a name. In the paper Opportunity Cost Neglect, researchers found that people often overlook the alternatives they give up because those costs are invisible.

People notice the meeting added to the calendar, but not the conversation that never happened or the hour of rest that quietly disappeared. The real cost of a choice is often felt in the life it crowded out.

Check your ROI

Taken together, materiality, depreciation and opportunity cost become tools for better judgement. They help answer simple questions: what deserves my attention? What am I neglecting? What am I giving up by choosing this?

Those questions matter because attention and energy are scarce assets. Once spent, they cannot simply be topped up next quarter. Small choices — another late evening at work, a rushed meal or pushing rest down the list — may seem minor on their own, but repeated often enough, they shape the life being built.

That is where return on investment becomes useful beyond finance. Not every worthwhile return appears as profit. Some pay back through stronger relationships, better health, more energy or simply the sense that time is being spent with purpose. What are you investing in?
