There was an entrepreneur of some Web 1.0 company - I think it may've been Excite or Paypal - who said that it was very important that you "celebrate your victories" as you found a startup. That's really important. Launching a product is a victory. So is fixing that really tough bug. So is implementing a feature, no matter how small. So is hiring a key engineer or closing a round of funding. So is coming up with an idea or hypothesis that seems plausible. So is getting a user and keeping him engaged and happy.

You need a lot of these little victories to have a successful business. But that doesn't stop them from being victories. And when you set your scale small enough, some of them are basically guaranteed.
