Internet fist bump to the entrepreneur who, in April 2017, asked me how to go about doing an extremely ambitious company and who has sent 2 years worth of updates titled: $COMPANY: $MONTH $YEAR The last one: "We did it! Finally have $NUMBER in the bank!" (Now the work begins.)

The choice is never "build vs. buy". It's "build 120%", or "buy 80% and build 60%"

The Cantillion Effect says that when new money enters the economy, it's better to be 'close' to the money than far away from it. Think of a Spanish galleon arriving full of silver, it's better to be working near the port than on the farm. 1/
