Skye is a wonderful place but I don't think it always represents freedom. The largest employer is the public sector (local government etc) followed by tourism, which (some would argue) tends to promote a non-confrontational attitude that exploits - even in an undoubtedly well-meaning way - the traditional ethos of hospitality. As in many other parts of the Highlands, several local houses on Skye have been bought up by rich incomers, to 'live the dream'... Nice for some, but not very 'free spirit'...
Also, one of the several possible meanings for the island name Skye is 'isle of clouds' or 'misty isle'. It's not a place where 'clear blue sky' is frequently apparent. Still magically beautiful, however....
And - re Lili's post - how does 'wisdom' 'come with' the Moon?
