After four years of working on the ChooseFI podcast, Brad and Jonathan want to share their lessons learned, the list of things they might do differently, and highlight a few episodes to re-listen to. Brad is back in the studio after missing out on Episode 290 with Paul Merriman. He's doing fine and appreciates everyone's concern. With Paul Merriman's Ultimate Buy and Hold Portfolio strategy, the thesis is that diversity is great, but own equal amounts of all asset classes versus a cap-weighted index fund to capture the growth potential of small companies. Unfortunately, for the last 12 years, the majority of growth has come from large companies. Brad says Paul's book reads like a FI manual with a high-level overview of small steps that could be million-dollar decisions. The decisions are not little. As discussed in Brad's The FI Weekly email this week, the Rule of 72 states how long it will take you money to double at a given rate of return. 72 divided by the rate of return is how many years before the money doubles. For example, 72 divided by 8% equals 9 years to double your money. The impact of that last double can be worth millions, that's why getting started early is critical. If your new and haven't already, today is the day to start. Jonathan agrees Paul's book is a great FI primer and was surprised by how much he enjoyed reading it. He says it would make a great gift. ChooseFI often talks about the aggregation of marginal gains. It can be quantified as each half a percent improvement means we can make an extra million dollars. Come up with 10 and that's an extra $10 million over your investing lifetime. If you can't do all 10, pick three or four and implement early, aggressively, and consistently. If they could turn back time and look at how their own understanding has grown and developed over the last four years, what would the conversation look like from both micro and macro views? Starting with investing, in the beginning, the most powerful concept inspired by JL Collins was to avoid the fees, a sentiment echoed by Paul Merriman as well. Diversity and time in the market are also key. You will lose approximately 40% of your total net worth when invested with a financial advisor at 1% in a mutual fund with a 1% expense ratio. The dramatic loss happens when your gross 8% market return is reduced to just 6% after fees. In Episode 052 with Todd Tresidder, he highlighted that there are three asset classes you could invest in, paper, like the stock market, entrepreneurship, such as starting your own business, or real estate. Inside of paper assets like the stock market, Todd says complexity can be valuable, but others like Big Ern and Rick Ferry say most people will do far betting sticking with something simple they understand. It's important to talk about the things that will increase the likelihood of success then discuss nuance. While Brad craves simplicity, Jonathan enjoys learning more. There's no one right answer, only what works for you. Jonathan always conflated individual stock purchases with day trading, but episodes with Brian Feroldi helped him realize they are not the same. For Brad, individual stocks always seemed like gambling. While he doesn't advocate having a huge percentage of your net worth in individual stocks, it's no longer the 0% he would have advocated for years ago. The software available through M1 Finance allows Jonathan to implement the complexity associated with some of these strategies and maintain them simply. As for investing in entrepreneurship, it has become something Jonathan loves doing. It's an investment he has total control over, as discussed in episodes with Alan Donegan after he pointed out entrepreneurship was left off the Pillars of FI list. After a disastrous real estate failure in his 20s, Brad learned real estate investing can be a significant part of his portfolio if you are investing and not merely speculating. He now owns two single-family rental properties which have been s
