The big turning point in my trading came when I made a decision and vowed to NEVER EVER let a loss exceed 8%. During the next 5 years I averaged 220% per year for a total compounded return of 33,500%. It's been 28 years since and I have never broken that discipline not even once!

1/ new essay: What's next for marketplace startups? Reinventing the $10 trillion service economy, that's what. Co-authored with @ljin18 https://t.co/fgKbrHTnH5. A short thread 👇

2/ Marketplace startups have done incredibly well over the first few decades of the internet, reinventing the way we shop for goods, but have been less successful services. It's bc services are complex, subjective, fragmented, and often in real life. Makes it hard

3/ There's been 4 major eras at making the service economy work online. The Listings Era, the unbundled Craiglist era, the Uber for X era, and the Managed Marketplace era

4/ Each era has added more value than the last, and utilized technology innovations, from internet to social / "read/write web" to mobile. The "Unbundling Craigslist" era was particularly epic at generating startup ideas

5/ The problem is, all the low-hanging fruit has been picked off. The techniques that got us to here won't get us to the next phase. So we have to do some pretty different things. That's why "Managed Marketplaces" have been a big deal - hire folks as W-2s, certify quality, etc.

So, today, for the first time in 25 (!) years of Apple, I downgraded. From the 2016 MacBook Pro to my 2013, which I had kept in a drawer...

It was pretty simple to do—Apple Time Machine backups let me do it with one click.

That first tweet captures, in two pictures, how badly Apple has “lost the plot” (to quote @wylieprof). On the right is the Apple MagSafe adapter, from 2013. On the left, what I had “upgraded” to.

Thanks, Apple! I really was nostalgic for worrying about yanking my computer off the table.

Oh and I really appreciated not knowing if my computer was charging. What was great was the little whoop sound you used, so that the speaker before me could be informed I was charging my laptop.

1. The major problem most startups face is marketing and the ability to carve out a niche, find and retain paying customers.

Even with a stellar developer team and a stellar product, your startup may not grow or survive without a great marketing and sales teams.

2. Start growing your audience before you’ve a product or an idea.

You should start promoting yourself and building your audience before you have a finished product or even before you have a great idea that you want to build.

3. Don’t wait to start building your audience after you’ve launched a product.

Most first-time developers actually ignore marketing.

They’re oblivious to the challenge of attracting people to take a look at something they’ve created.

4. At least until they see their first project crash and burn within hours of the launch.

There are so many times that I have seen developers spend countless hours building something, releasing it with no fanfare...

5. and only then trying to figure out how to promote it by asking marketing questions on Indie Hackers, Quora or Hacker News. Don’t make that mistake.
