>I would say working less for money is the single biggest thing people can do to be more productive, or to have more time.

moving closer to work has similar effects on your free time without cutting in to your free money.

but yeah, I agree. It's hard to have time to work on your stuff if you work 40 hours a week, especially if you need some family or social time. working part time helps a lot, if you can pull it off. Again, though, be mindful of the commute and reduce the number of days a week you work rather than reducing the number of hours a day you work.
