Get a contract. The hard truth of life here on Earth is that not everyone is cool and nice and honest. We’ve been lucky, and found about 90% of the people we’ve done business with are great. But there have been a handful of people who have tried to fuck us, and a couple have been successful. It’s a hard lesson to learn. When you’re starting a business you have to be almost impossibly optimistic, because there is a new problem to fix almost every day, and if you let them get you down you’ll get depressed and fail in a month. But that optimism can blind you to the motives and dishonesty of that 10% of our species that seems to consist of shitheads. So now we always get a contract, regardless of who it is. We never want to rely on the kindness of strangers for the health of our business.
