Did you read “Ruth Bader Ginsburg’s Advice for Living” in The New York Times?
“Work-life balance was a term not yet coined in the years my children were young; it is aptly descriptive of the time distribution I experienced. My success in law school, I have no doubt, was in large measure because of baby Jane. I attended classes and studied diligently until 4 in the afternoon; the next hours were Jane’s time, spent at the park, playing silly games or singing funny songs, reading picture books and A. A. Milne poems, and bathing and feeding her. After Jane’s bedtime, I returned to the law books with renewed will. Each part of my life provided respite from the other and gave me a sense of proportion that classmates trained only on law studies lacked.”
This makes so much sense. And, I don’t think you need to have children to create this “work-life balance.” The first time I achieved this, I was attending portfolio school and working part-time (24-32 hours/week) at a bookstore. My week broke down to 4 days attending classes and working on school projects and 3-4 days at the bookstore. I was rarely tired even though every single day of the week I had to be somewhere or mark something off my to-do list: “each part of my life provided respite from the other.”
You should try it. I know I am trying it again.
