Solitude and creativity

Karl Lagerfeld said this in Lagerfeld Confidential:

'People who do a job that claims to be creative have to be alone to recharge their batteries. You can’t live 24 hours a day in the spotlight and remain creative. For people like me, solitude is a victory.'

And recently in Brain Pickings, Bukowski was quoted:

'When failures gather together in an attempt at self-congratulation, it only leads to a deeper and more, abiding failure. The crowd is the gathering place of the weakest; true creation is a solitary act.'

Which inspires me to dump more quotes on solitude and creativity:

Organizations for writers palliate the writer’s loneliness but I doubt if they improve his writing. - Ernest Hemmingway

Artists work best alone. - Steve Wozniak

One can be instructed in society, one is inspired only in solitude. - Goethe

Without great solitude no serious work is possible. - Picasso

I love my me-time but that doesn't always translate into productive work. Tsk tsk tsk.
