For the last 9 months, I've spend 60-80 of those hours each week putting conscious attention to items directly related to founding my company. Let's call that "work."
But you can also call it "creation." Most of this time I am outside my self. What is being drained or used?
What is different in the time I am not "creating"? My mind is still doing things. What is the difference between "writing the marketing section of the business plan" and "reading a novel"? Does one use less mental energy than the other? I've read so many novels in my life, I'm tired of them. I don't like the way they lock my mind into their train of thought. Reading the novel becomes draining. TV is pure hell. Better to create, to engage in the intricate dance of love and passion with my Muse.
I do take a nice nap in the middle of most days. And it is nice to watch the birds flying in the valley, to lift big heavy things, and to eat good steak.
