I've just finished viewing the 7 1/2 Habits Of Highly Successful Life Long Learners, http://www.plcmc.org/public/learning/player.html.
The habit that comes easiest for me is habit #2, Accept Responsibility for Your Own Learning. Whether it's at work or in my personal life I seek out ways to keep learning and become better at what I do. As my role as a special education teacher has changed over the years I have sought out ways to continue learning including seeking out staff development, learning from co-workers or observing successful classroom teachers.
I don't always "begin with the end in mind" (habit #1), and as a life long learner I don't alway think that is a bad thing. Some learning, like going back to school to get my library certification, has a very clear end in mind. For me, sometimes the end doesn't become clear until I've learned a little. Like the 23 Things. I have no idea what I'll be learning but somewhere along the end will become clear....I think.
