Going into business is risky in and of itself. It may not work, and it won't. What will you do when things go wrong.
I'm not talking about having to close the doors of the business, but when bad things happen how will you respond to it. Will you panic and prematurely close the doors to it? Or will you buckle down, cut back spending, and increase income?
The choice is yours. How you respond, and play your cards makes all the difference in the world.
