If you have written 179 books, been on Guinness book of world records - would you not take some chill pill and enjoy your time?

Danielle Steele - the author of 179 books still works 20 hours a day.
I keep working.
The more you shy away from the material, the worse it gets. You're better off pushing through and ending up with 30 dead pages you can correct later than just sitting there with nothing," she advises. Her output is also the result of a near superhuman ability to run on little sleep. "I don't get to bed until I'm so tired I could sleep on the floor. If I have four hours, it's really a good night for me," Steel says
Coming back to the work-life balance debate, I believe the biggest mistake in this entire conversation is when one’s work and life are totally different. For e.g. X is a banker and X also plays guitar during the weekends.
X is going to get frustrated very soon as he/she moves up the corp ladder and finds it difficult to get the work-life balance.
