When you fail, don't blame others.

One of the biggest mistakes founders make is to blame others for their own failures. Wallow in self pity over what they think the competition is doing wrong, commiserate in misery and get dramatic.

This reeks desperation.

Product market fit is hard. Timing is hard. Message is hard. Building is hard. Funding is hard. And most will fail, even if they truly believe what they made is amazing.

They are your mistakes, learn from them. Try something different.

Bitching won't build the future or advance yourself. Customers don't like beta energy.

Big boy pants, and go build.
