What I learned in interviews with the young and the old, the successful and the unsuccessful.
I sat down with 30 professionals between the ages of 28 and 58, and asked each what they regretted most about their careers to date. The group was diverse: I spoke with a 39-year-old managing director of a large investment bank, a failing self-employed photographer, a millionaire entrepreneur, and a Fortune 500 CEO. Disappointment doesn't discriminate; no matter what industry the individual operated in, what role they had been given, or whether they were soaring successes or mired in failure, five dominant themes shone through. Importantly, the effects of bad career decisions and disconfirmed expectancies were felt equally across age groups.
