There is a reason you, as an entrepreneur, are passionate about building something that’s hopefully better at solving the problem.
I really hate the advice of don’t build something before validating. That has literally never worked for me. That’s like asking a leading question and shooting yourself in the foot at the same time.
You should have some conviction why you’re doing something. Don’t one of those people who tries to do something in an industry they have zero clue about (99% chance of failure). If you know what you’re doing you should have a 60% plus chance of success.
It’s so easy to sell something that people just get at first glance because it’s actually good at solving their problem, because you had faced that same problem and decided to do something about it.
