As an academic, I am a professional learner--I can't teach about advances in my field if I do not know about them myself. Therefore, constant reading and learning are part of my job. I schedule reading time every day--even highy packed very busy days afford at least few minutes to skim a journal article-- and on many days I schedule an hour to read a textbook chapter. Saturday is my "read for pleasure" day--I never read job related material then. That's my day for reading history, biography, gardening books, even the occasional romance novel.
A few ideas that work for me:
1. When I go through a professional journal, I tear out articles I want to read, and put them in a folder on the front seat of my car. When I have to wait somewhere (say, at the dentist's office, or when sports practice runs late), I can do a little catching up.
2. Recorded books and lectures are worth their weight in gold, expecially if you, like me, spend much time in the car. About half the time I listen to lectures recorded at medical or nursing conferences, and half the time something on an unrelated field (music appreciation, history, a novel). Even in only 15 minutes of listening a day, you can learn a considerable amount in a month or two.
3. If I'm reading something important for my job, I always read with a highlighter or pen in my hand to mark important passages--it helps me focus on what I am trying to learn. Even if I never go back to that article or book again, having marked what I wanted to remember helps me remember it.
