We love seeing LeBron pour everything into maintaining his performance. I bet if you asked him, "Do you want free wins next year cause you're the points king?", he'd say no. Our top marginal tax rates need to be very high (like they used to be). Make America Sports Again.

Stored wealth is an incredible double-edged sword. The appeal of a sustained advantage is a powerful incentive, but of course having that advantage disincentivizes effort at the margins. Imagine if LeBron got free wins next year for successes in previous years. He'd be fatter.

Wealth accumulation creates a sustained advantage that is clearly anti-competitive. Sports show us that collective progress and peak top-end performance comes from level playing fields with zero sustained advantage. Winners have to prove it from scratch every single time.

Why, @gmail? You have this nice row of checkboxes... and then this almost-checkbox pushed a few pixels left of the row. Ugly *and* confusing.

Funny about building with Cursor/LLMs -- they have no idea how long it takes them to do stuff. It'll make a project plan that says "4 days" and then implement it in 10 minutes.

Since ~2005, we’ve seen a huge rise in home music production with self-taught ppl creating quality releases that gain commercial traction. Seems the same thing should be happening in movies - that YouTube would be teeming with dramas shot on iPhones - but it’s not. Why?

Just went kart racing at @k1speed. Super fun but now my neck hurts and I’m watching racing videos on YouTube in the middle of a sunny afternoon. Asked ChatGPT what I should do to improve my lap times, and it wrote “bruh 😒 smdh” What head, ChatGPT. Bet you can’t race for shit.

A great thing about language is how a MARATHON is a running 🏃🏽‍♀️ race, a TRIATHLON is a running 🏃🏽‍♀️ , biking 🚴🏼‍♀️ , and swimming 🏊🏼 race, and a BIATHLON is how you prove you can hunt in the nordics during winter ⛷ 🔫. Biking 🚴🏼 + swimming 🏊🏾‍♀️ race is called AQUABIKE, obviously.

Proud of the work I did with the @splitwise team. I'm a personal trainer for startup hiring. If you're an early-stage founder who wants to hire like the best, get in touch. #startups #Recruiting

Apple’s implementation of “Low Power Mode” is bullshit. It should be a slider instead of a toggle (how much do you want to optimize for battery vs performance) w/ estimate of hours remaining based on your usage patterns. And it shouldn’t reset after charging.

I've been working with @rrwhite and the @FathomDotVideo team for a few months and am thrilled to see they were rated #1 for customer satisfaction across all software products on @G2dotcom this year. If you haven't tried their AI assistant yet, you definitely should.

Many early-stage founders try to give the job of candidate sourcing to someone else far too early (sometimes when their teams are <5 ppl!). Founder sourcing is instrumental to hiring the best possible talent in early stage startups. I wrote about why: https://t.co/2A6dqffAhe

I’ve made or seen hundreds of hires, and one thing I have never seen is a B player hire an A player. Not once. If you play that out, you realize that compromising on even a single role can destroy a team forever.
