If you like to learn about some things, or pretty much anything, like business, politics, economics, communication, and more, Blinkist can probably help you.

The team at Blinkist summarizes the key points of thousands of non-fiction books and turns those summaries into audio you can listen to on your commute, while you're exercising, or pretty much anything else. They even offer a free plan with which you can listen to books they have pre-selected.
