It used to be said that you were on the fast track if you were earning your age; i.e. earning $25,000 by the time you were 25, $30,000 by the time you were 30, etc.
With inflation, you could probably triple those salary numbers to see who is on the fast track at various ages.
But most people reach a plateau in their careers. Very few of us make it to the board room or top management in whatever field we are in.
I’m just over the six figure mark and have been interviewing to keep my skills up. The interviews go well until they find out how much I currently make.
