Any Failure Stories?

Often looking through Reddit, I am just confronted with a ton of "successes". It can be motivating at times, but sometimes it just feels plain unrealistic.

I'm particularly curious about people who have gone all out on their SaaS—whether that entails quitting your 9-5 or throwing an exorbitant amount of capital towards the project, only to be met with little traction or no results.

I realize these are harder and perhaps less fun stories to share, but, at least in my opinion, they provide more to learn from than the successes.

So... what's your failure story?
