Check out my blog for my most recent writing.

I write so that I can understand. I find that confusion can sneak in if I just read or only think about a concept. Forcing myself to write down my thoughts exposes weak areas in my thinking.

The second reason to write is to pass on what I’ve learned. I owe a lot to generous experts that have shared their knowledge and expertise. I’d like to pay it forward.

The two areas that I currently write about are endurance training and value investing. At first glance, the two subjects seem disparate. However, the two have a lot of common ground:

  • Compound interest is the eighth wonder of the world: Building on previous gains is an incredibly powerful force;
  • The long game is the key to success. Gains made over the long-term are more stable and persistent than quick fixes;
  • Natural principles govern progress. And anyone that has a shortcut is selling something;
  • The lottery mentality is a tempting dead-end, despite what popular magazines’ top-10 lists would have you think;
  • The devil is in (skipping) the details. The aggregation of marginal gains pays big dividends;
  • The most effective methods are demanding and unpopular;
  • Cognitive biases account for most of the big mistakes;
  • Fear and greed are your friends, but only if you invert what they tell you: “Be fearful when others are greedy and greedy when others are fearful.”
  • It’s not the ingredients, but the cooking that’s important. The keys to long-term gains are well-known; secret ingredients don’t exist. The big differences come from how the ingredients are combined; and
  • Using salt doesn’t make you a cook. General knowledge in any subject–which includes popular media and retail salespeople–is shockingly basic. Seek out esoteric, high levels of expertise to learn from. And accept that it’s exceedingly hard to find.
