When I was 30, I earned $60K pa, owned nothing, rented a HUDC flat, had a Mitsubishi Lancer and net worth of about $130K

When I was 40, I earned $210K pa, owned a 3-bedroom condo, had a BMW 316 and net worth of about $1m

At 50, I earned $700K pa, owned a landed property, had a Porsche 911 and net worth of about $4m

Today I have net worth of $12.5m

Point is, things can change dramatically over time. What you have at 30 is little reflection of how things will turn out.
