The best things in life sustain themselves over time. Whether it's relationships, investing strategies, careers, or habits – if it can't go the distance, I'm not interested. I try to write about those concepts in plain English. No jargon, no fluff. Just honest insights on enduring concepts in investing and life. I've blogged on and off for the last several years and this simple site has what I consider to be my best, most enduring writing. I'll continue to update over the coming months with more content as I dig through the archives. # About Me For the past 15 years, I've been active in climate tech and sustainability and have seen it from all different angles. - Finance at the first renewables only retail provider and subsequent acquisition - Product executive at Choose Energy with successful exit to Red Ventures - And now, private equity investing.
