Islands are cool for a couple of reasons
Firstly, there is no escape. Everything on offer occurs within a limited surface area, and as a result, there is an active investment in every aspect of the history and terrain the land has to offer.
There is no getting away from the ocean. Plenty of soulful sunsets and unavoidable climate patterns. The sea breeze brings with it a volatility to coastal weather and enough mist to render the plants clinging to the cliffs lush and green and damp. For someone with enough time to lose themselves along the footpaths, being close to the ocean doesn't hurt.
I also enjoy the social spinoff that occurs on an island. Being unable to avoid other people creates a strong sense of community and culture, which is preserved even under heavy tourist footfall. I believe that there is merit to the argument that face-to-face social interaction creates a healthier and happier hometown.
Jumping between islands the way that I am repeatedly indicates that 1) close-knit living and 2) a forgiving pace of life allow for the protection of local heritage.
Islands are cool, and they're teaching me a lot.
