What theory is evidenced when someone claims they could achieve greatness through sheer determination?

The claim that someone could achieve greatness purely through sheer determination aligns with the concept of wishful thinking. This theory suggests that individuals believe in the possibility of achieving positive outcomes based on their desires or hopes, rather than a realistic assessment of the situation. When a person emphasizes determination as the sole factor for success, they may overlook other significant elements such as skill, opportunity, social support, and various external circumstances that also contribute to achieving greatness.

Wishful thinking encapsulates the idea of aspiring for success while disregarding the complexity of reality. It reflects an optimistic perspective that can motivate individuals but may also lead to unrealistic expectations and potential disappointment if other factors are not taken into account. By believing that determination alone is sufficient, one embodies the essence of wishful thinking, affirming that they can attain their goals simply by wanting them strongly enough.
