I've been tracking a specific metric that I find more motivating than net worth or account balances: how many months of expenses could I cover if my income disappeared tomorrow?

I call this my 'financial runway.' It includes emergency fund, liquid investments accessible without penalty, and any other accessible cash.

At the start of my financial journey: 0.5 months. One layoff away from financial crisis.
After 2 years: 3 months. Breathing room but still precarious.
After 5 years: 14 months. Real cushion. First time I could take a career risk.
Now at 8 years: 31 months. Can weather a significant career disruption or choose to work on something without immediate income.

The financial runway metric converts wealth into something intuitive — time. Time to find a new job without desperation. Time to start a business. Time to care for a sick family member without financial panic.

Every dollar of savings is a day of freedom. That framing has been more motivating to me than any savings rate target.
