This episode is brought to you by House of Macadamias delicious and nutritious nuts! I love macadamia nuts and have been enjoying them often since keto expert Dr. Dominic D’Agostino recommended them on the podcast in 2015. They taste great, and with more healthy, monounsaturated fat than both olive oil and avocados, 27% fewer carbs than almonds, and more than 50% fewer carbs than cashews, they’re the perfect low-carb, keto-friendly, nutty snack. In fact, I just ate a handful of lightly white-chocolate-covered macadamias about an hour ago to keep me going through the afternoon until dinner. And I will say this: House of Macadamias produces the best-tasting macadamia nuts I’ve ever eaten… by far.

Now, listeners of The Tim Ferriss Show podcast can use code TIM20 to get 20% off all orders and a free box of their best-selling Namibian sea-salted macadamia nuts worth $35! If these are not the best macadamia nuts you have ever eaten, House of Macadamias will give a full 100% refund, guaranteed.

Want to hear another episode with an investor of cutting-edge insight? Listen to my conversation with Benchmark’s Bill Gurley, in which we discussed sell-side analysts versus buy-side analysts, financial models, repurposing good ideas for alternative applications, the conviction of network effects, undervalued competitive advantages, cultivating anti-tribalism, America’s future, and much more.
