I'm a senior in uni right now, and also a member of a business frat so I know a ton of people in finance/consulting, the classic poster child professions for early burnout.

We had a guy come give a talk two years ago about his work, and it ended up being sort of a life/success story and it was absolutely fascinating: he had done a variant of exactly what you describe, on for a few years, off for one or two to reset and explore passions, rinse and repeat.

The applause he got from our graduating seniors was very telling.
