| 0:00.0 | Hey, everybody. Welcome to the 10% Happier Podcast. I'm Dan Harris. We are, as many of you know, |
| 0:09.1 | living through a riptide of wellness misinformation, just like a tsunami of bullshit. Much of it |
| 0:16.4 | coming from people like RFK and members of the Maha or Make America Healthy Again movement. |

| 2:03.1 | Summer's almost here. It's time to plan for that big vacation, but you don't want to be worrying about whether you can afford it. I can tell you |
| 2:07.7 | somebody tends to worry about all things financial, that having my finances organized in a clear |
| 2:14.2 | and logical way and a one-stop way in a centralized way really reduces my anxiety |
| 2:22.4 | and makes it easier to plan for things like summer vacations. Monarch is the personal finance app |
