Everybody leaves eventually, especially artists of one form or another. If the call of a new pasture in which to paint never calls then how does new and exciting work happen, the imagination after all is only as strong as the individual and no artist can imagine a waterfall crashing down upon shaped boulders if they have never seen a water drop.
Some leave too soon, some perhaps too late in the day but neither really ever write a song, paint a picture, or capture the emotion of leaving somewhere they love unless they have a poet’s mind dwelling deep in their soul.
