I take advantage of my local library, both going in to the building to choose physical books, and browsing through their online caralog to pick ebooks or audiobooks. This way, I come across so many books outside my usual interests, or even outside my comfort zone. I schedule my Learn and Study habit to coincide with my mid-morning coffee break; and even though I only read for ten to twenty minutes, I enrich my life so much through what I've learned! So far, I've read books like "Hidden Figures" and "Rocket Girls," the history of women "computers" in the space program; books on art and creativity ("Expressive Flower Painting" by Lynn Whipple); books about presidents ("Theodore Rex" for one) and the head ushers of the White House ("Upstairs at the White House"); cookbooks ("You've Got It Made," "Mastering the Art of French Cooking") and even a book about writing a cookbook ("As Always, Julia")! In short: I just dive into the library or a bookstore, and look for something I'm interested in, or something I know nothing about, and commit to spending ten minutes a day learning about it. It's an awesome habit, and I love it!
