I've been pondering around what it actually means in practice to find product market fit, and also what defines an MVP? I would like to know your thought, as I understand those theoretically, but I seem to struggle with this idea in practice, as I often found that it's very tricky to know when to draw the line of how "minimal" an MVP should be? and when should I say that the idea is bad that I am testing is bad, and after how many iterations should I just give up on the idea, or know if I should still pivot? Interested to know your thoughts.
