Quest , is a powerful word with regards to life.
At the end of the day, you will love the results on what you work on:
It is not so bad to live like an outcast on an island once in your life, because you would definitely learn how to survive like a natural human being.
Life on island can be fun and boring to some people, just depends on how they see life, and of course with the current technology it may not be their option to go for. I took the path because I really needed some adventure in my life, I have lived both life and I think it is always nice to take a break from the technology the society provide for a while.
enjoy nature, be with nature.
