Success is a journey, especially when it comes to your finances. One of the most common obstacles in our financial journey is dealing with high interest debt.

Thanks for having me back. So nice to see you.

You too, Tim. You were first on How I Built This back in 2020 And as always, for anyone listening, if you haven't heard that episode, it's so good. We'll put a link to it in the episode description. So check it out. In that episode, Tim, we talked about your time as a student and learning Japanese, and how you got a sales job at a college, and then you started your own business, a supplement company. And then, of course, you published your first book, which many people know you for the four-hour work week. And initially, you couldn't even find a publisher.
And the story of how you managed to use your blog, to get it out there, and sold millions of copies, became a massive best seller. And of course, since then, you've written several other books. You've launched a massively successful podcast, which hit a billion downloads last year. Congratulations.
