Why is net worth compared to a financial thermometer?

Net worth is often compared to a financial thermometer because it provides a clear, measurable indicator of an individual's financial health, similar to how a thermometer measures temperature. Just as a thermometer shows how warm or cold something is, net worth reflects the balance between assets and liabilities, indicating whether someone's financial situation is improving or declining. Monitoring net worth over time helps individuals assess their progress toward financial goals and make informed decisions about spending, saving, and investing.
