1. Circumstances, influences, stresses, and competitive, cultural, demographic, economic, natural, political, regulatory, and technological factors (called environmental factors) that effect the survival, operations, and growth of an organization.

2. Sum total of all surroundings of a living organism, including natural forces and other living things, which provide conditions for development and growth as well as of danger and damage.

If you want to become an entrepreneur, you must learn how to deal with ambiguity and even thrive on it. There is very little structure in startups when it comes to things like business model, client base, work environment etc.
