Good advice from Laura Vanderkam:

Instead of resolving to achieve work–life balance, it’s better to ask this question: What do I want to do more of with my nonworking time?

When I ask people this question, certain answers come up a lot. People want to exercise more. They want to read more. They want to get together with friends. They want to volunteer. This is what people are talking about when they say they want to be “balanced.” We presume that making space for these enjoyable activities requires working less, but the truth is that there are plenty of people with challenging jobs who exercise, read, and have meaningful relationships with their friends, family, and community.

Instead, making space for these things requires being better stewards of time. It means resolving to spend nonworking time on higher-value things, rather than easy things, such as turning on the TV. The best way to do that is to be a bit more strategic about the 168 hours you have each week.
