I love listening to podcasts and books on Audible when I'm traveling. In the car or on a plane, they help pass the time and if I always find some nugget of learning or inspiration. One of my favorite Podcasts is The Tim Ferriss Show. Tim has done a masterful job interviewing many of the thought leaders across a variety of genres. His show is full of educational nuggets ranging from personal growth such as meditation and food to business topics like leadership. You can see my podcast list here.
I also love reading books, I remember when I was a kid our school had a summer reading program and my sister and I always had our nose in a book. Probably more about seeing how many books we could read as opposed to a love of reading. Regardless that program instilled in me a love of reading. I still read quite a bit today. You can see my reading list here. This is obviously a work in progress as I'm adding to it frequently. I haven't actually counted but I'll bet a read or listen close to 100 books a year.
