You must figure out how you deliver real differentiation. What you’ll stand for, be known for. You have to have a core. You can’t let the market machinations and press proclamations worry you. The big guys can’t crush you as easily as others think. Be a cockroach. Be indestructible. And remember that competing with the big boys is not for wimps. Fight hard. No cry babies.
