Economic issues are the easiest. This is simple - if the economy is booming, your business will have a better shot of succeeding because people have more money to spend. If the economy is bad, you will likely have to be more aggresive with pursuing sales. If you are in real-estate, for example, the economic activity of the housing market can make or break your business. All businesses rely on the economy to dictate how much money people have to spend on goods and services.
