Ask HN: Not trying or not knowing when to stop?

[Philomath]

In my personal experience I've always complained about not trying a bit more to get some projects to succeed, but in the other hand, I've heard of so many people that tried for too long when the project was already dead. What do you think?

What's the question? So far you've listed two things at not-quite-opposite ends: not applying enough effort to succeed, and not knowing when (or why) to stop.

It depends.
