This is an important question for entrepreneur - should continue with the business concept or change shift.  The key here is questioning the concept/the logic for the business. Were the assumptions correct.  Some businesses are the result of pivot.  Like Twitter.  It started as Odeon but a shift has to be made, into microblogging site when Apple launched its own podcasting site (can you fight Apple)  So you go to a blue ocean where there are no competitors.

Even Groupon started as a platform for non profit.

It is about learning from the past, keeping your foot firmly on the ground as you learn from your mistakes, while shifting direction.  It is really a pivot.
