Lisa Neal’s put a nice list of hints and tips to be a better elearning professional. Her tips focus on how to get deeper into formal learning, which Scott Leslie expands in a comment.

The point being, you’ve got to be a consistent and persistent self-learner, which is a meta-learning topic. Things are dynamic and changing, and you’ve got to keep pushing the envelope. It takes little time (Lisa’s talking about 10 minutes per day), and yet it may be the best investment you can make personally. I’ll also argue that helping learners to learn (what Tony Karrer calls “building learning skills”) is probably the best investment an organization can make!
