Luck
Luck, or lack thereof, and timing, or lack thereof, are keys. You DO have to be in the right place at the right time to have any sort of successful career.
I think so many people suggest instructing because it is the easiest job a low-timer can get. It builds time, it pays (somewhat - some jobs are better than others) and it puts you together with all kinds of pilots. Pilots just like you who are building careers and can network or share information. Other pilots who know people. Other pilots who want you to instruct them in their brand-new, shiny Baron. Not too many places will hire a new multi-engine pilot out of the chute to fly their airplane because of insurance.
Once again, best of luck in your career.
