Listening to Apple Podcasts is a productive and rewarding way to spend your free time. Whether you choose to listen to them while you're driving, walking or hanging out in your room, the three podcasts below will expose you to worldly topics and provide advice on ways to seek happiness and achieve success.

1. How I Built This

In NPR's How I Built This, Guy Raz gets the inside scoop on some of the most widely known companies in the world. He interviews innovators and entrepreneurs and explores how their life journeys have led them to renowned success.

Whether you listen to the episode featuring the creator of Headspace (the guided meditation and mindfulness app), the founder of the Peloton Bike, or the inventor of Dippin' Dots ice cream, I guarantee you'll learn something new and fascinating. Listening to How I Built This provided me with a sense of ease that not all people who achieve success start at the very top, but rather work their way from the bottom up.  

2. Happier with Gretchen Rubin

If you simply wish to be happier (who doesn't strive for a little bit more happiness?), then this podcast is for you. Through personal stories and experiences, Gretchen Rubin gives realistic advice on how to live a more joyful life filled with laughter, health and gratitude.

In one of her most recent podcasts (Episode 253), Rubin explains how to keep your New Year's resolutions -- for real this time. Happier's uplifting and encouraging tone boosts my mood when I'm struggling or having a rough day. Rubin's practical advice, such as thinking about the Solomon Paradox when dealing with a difficult situation (Episode 247), will give you the necessary tools to become a more positive person.

3. Kwik Brain

Jim Kwik coaches his listeners by providing practical tips and brain hacks to help those with busy lifestyles to learn and achieve anything in a quick and more productive way. The brief 20-minute episodes will guide you in making simple, yet profound changes in your life.
