Go back to the beginning
Remember when you first started your business? Why did you do it? What made you think it would be successful? What problem did it solve for people? How was it going to provide a return on your investment (both time and money)?
So often, as entrepreneurs we forget all these things. We get so caught up in our day-to-day stuff, our plans for going forward, the implementation of dozens of "half-baked" ideas, that we lose sight of why we did all this stuff to begin with.
Go back to the beginning. Go back to where it all started and identify your purpose, your plan and your intent to do something great. Don't move on until you have re-identified these things.
And if for some reason after days, weeks or months agonizing over those questions you feel like you can't answer them, either find a way or find something else to pour your time and money into.
