I define a successful career as one in which happiness and fulfillment play as important a role as money and prestige. After two decades in business, I’ve singled out three qualities that people who meet this definition have in common.
1.) They’re close to their colleagues.
It’s estimated that the average Joe and Jane will devote around 90,000 hours of their lives to work. That in and of itself is a solid reason to befriend your colleagues — I’d find life pretty unbearable otherwise — but there are professional advantages to consider.
