One of the best things about being an entrepreneur is that you don't need to close up shop if things are going wrong as much as you can pivot to an area of business you might better excel at.  But when do you make that change?  How long do you test your ideas to see if they'll take off or if you need to make a change?  I recently heard a podcast from Andy Stanley and he asked a great question: If before you die, you could have people walk in the door and thank you for something you did for them, what would you want them to thank you for?  Is the dream you're chasing something that would be part of that answer?  What would you sacrifice to see that come true?  How can you change to make that come true?
