That's why you don't go to isolated places like Maldives (unless you are utterly addicted to diving and surfing) but rather Indonesia... you can spend years travelling around discovering places, culture, people, food etc.
Met plenty of people stuck in travelling mode for years, but yeah they don't just lie around the beach (most of the time).
A 2 week project crunch can be exhilarating, but 6 months? No thanks!
Similarly a few weeks of beach vacation can be wonderfully relaxing, but months, years of "doing nothing" will soon become boring.
