What characteristic defines a great idea?

A great idea is fundamentally defined by its ability to solve a problem. This characteristic goes beyond surface-level appeal or superficial attributes. While aspects such as aesthetics, popularity, and ease of implementation can play significant roles in evaluating an idea, they do not determine its greatness.

The primary intention behind any great idea is to address a specific challenge or need effectively. For instance, an innovative solution that resolves a critical issue may not always be visually appealing or widely accepted at first, yet it can fundamentally change how that problem is perceived and dealt with. This focus on problem-solving is what elevates an idea from merely being good or acceptable to being truly great, as it has the potential to create meaningful impact and value.
