Sureness is something like a neck brace, which we clamp around our lives, hoping to somehow protect ourselves from the frightening, constant whiplash of change. Sadly, the brace doesn't always hold.
I was a writer before 'Eat, Pray, Love,' and I'll be a writer after it's over. It's what I want to do for the rest of my life.
My writing practice taught me the important thing is steadfastness. It's not necessarily discipline. Discipline can become a prison. When your spiritual practices become another thing for you to be anxious about, they've lost their usefulness.
I push every day against forces that say you have to go faster, be more effective, be more productive, you have to constantly outdo yourself, you have to constantly outdo your neighbor - all of the stuff that creates an incredibly productive society, but also a very neurotic one.
