I've never thought of learning as something that you have to DO---mostly it just happens for me. The easiest of the 7 1/2 habits of lifelong learners for me is #7---Teach/Mentor. I think that most of us do this naturally---really whether we want to or not! Because I think of learning as usually an informal process the hardest of the habits would be to set a goal and stick to it---#1 on the list (which is perhaps a bad thing for this exercise that I've gotten myself into! ).
We'll see how it goes and go from there---see? Already am avoiding that habit #1!
