The lessons
Things I learned the hard way, so you don't have to.
Selling. Don't make a free product. Don't sell to colleges, high schools, or broke students.
Deals. Don't do any work before the deal closes, and don't give away too much free value before it does. Go deep on every contract.
People. Pick the right team and the right co-founder. Treat everyone with kindness and respect. And be aware of the agenda someone might have when they come to you.
Go big or go home. A $500 client takes about as much effort as something that could make you $10 million. So go for the big one.
Small ones. Don't talk about wins before they happen. Don't connect with people you don't know on LinkedIn, it wrecks your feed.
