I think it boils down to being able to adapt. You need to constantly re-invent yourself to stay fresh. You also need to be ahead of the curve as far as what people want. If you are operating by the seat of your pants, you are just a mistake away from being out of business.
I don't have the secrets for achieving this but then each and every business is unique in that area.
If you have a solid business plan you can step up to success. I went into a Potbelly's sandwich shop today (I actually eat there several times a week.) There is normally a line to the door and it seems to be busier and busier every week. Damn good sandwiches.
What do they say about a successful business? Location, Location, Location.....
