Sell

Try to spend as much time selling as possible, especially if you are a technical
founder. At the beginning phase of a startup, I think the purpose of developing a
product is actually not to sell it but to teach me how to sell and understand
what's wrong with the product. The purpose of the product is purely
educational and hopefully allows me to learn from users' perspectives.

I keep telling myself that I should spend at least an equal amount of time and
effort on selling as I do on developing the product, and ideally more.

One recurring mistake I found myself making is that I spent way too much time
developing the product and way too little on selling. I often develop a product in
weeks and try to sell it in one day, only to find that no one signs up. Then, I think
the product is bad and go back to developing.
