Solitude and loneliness have recently become one of my main interests in painting and generally. Some inspiring thoughts about them:
"Solitude will be welcomed or endured or avoided, according as a man's personal value is large or small,--the wretch feeling, when he is alone, the whole burden of his misery; the great intellect delighting in its greatness; and everyone, in short, being just what he is."
from The Essays of Arthur Schopenhauer
"Remember: the time you feel lonely is the time you most need to be by yourself. Life's cruelest irony."
