Work. Work used to mean going out and finding/killing food, securing shelter, making clothing, etc. The value you were creating from your work was very direct and very clear. I doubt there were days when people just didn't "feel like" going to work. Now, working a corporate a job, I feel so far removed from the value I'm creating (if any). I am taking a more paleo-ish approach by leaving corporate life and starting a small business. Still a far cry from hunting/gathering, but I hope to feel a more direct link between what I'm doing and why I'm doing it.
A lot of what has already been said...better sleep, less technology, getting more in touch with nature and like-minded people.
I've got an overarching goal building in my head and I am beginning to be more aware of all these little pieces that will help me get there. The overarching goal is probably the same as many other people's goal: Be the Best Me I can Be.
