Final answer:
Entrepreneurs with an internal locus of control believe they can control their own outcomes and view challenges as opportunities, a critical belief in entrepreneurship.
Step-by-step explanation:
When entrepreneurs believe that their accomplishments and setbacks are within their own control and influence, they are exhibiting internal locus of control. This concept, as described by Julian Rotter, refers to the belief that individuals have the power over their lives. Entrepreneurs with an internal locus of control attribute their successes to their own efforts, and see setbacks as opportunities for growth and learning. This contrasts with an external locus of control, where individuals might attribute outcomes to external factors beyond their control. Entrepreneurship involves not only the willingness to take risks but also the belief in one's own ability to manage and influence those risks and outcomes.
