God put Adam to work (the first time)

Genesis 2:15

God put Adam in the garden "to work it." So one of Adam's purposes in life was to work the Garden. I think this is interesting in light of how we think of "work" today. Was this to be Adam's hobby? Obviously, there's no mention of a time clock here. I think there's an interesting contrast between work here and then after The Fall. This is something I want to explore more fully after going through other passages.
