It could have been written about any career path -- Some people who dedicate their careers to ascending in a single corporation regret it, Some people who aspire to be corporate lawyers regret it, Some people who become ski instructors to have more time to ski regret it.

Careers are long, and I think the key is to try things, learn what suits you, and generally try to evolve towards things that are a better fit for you.
