Work is important. Work is boring. But while work frequently gets described, it rarely gets defined. In many respects, work distinguishes us from other species. Unlike other animals, we have the ability to deliberately and consciously act upon the existing world and re-work it into something new.
Some people argue that, where work and life are concerned, one ends when the other begins.
But, actually, you are working long before you will ever work at a job. In fact, you are working all the time. After all, learning is work. Sustaining friendships and relationships is work. Caring for others is work.
