Speak truth to power (if you can get a word in)

This may sound like a broken record, but if you do not have a clear business plan, you are already setting yourself up for failure. A business plan could be just a couple pages long that describes what you would like to do and how you would want to do it. The important thing is that it will show how much you are willing to spend and how much profit you are planning to make and how long you plan on surviving before you break even. A business plan is like a road map not a prediction of the future.
