A quirk, or eccentricity, refers to a unique or unusual trait that distinguishes an individual or thing from the norm. These characteristics can manifest in various ways, such as peculiar habits, unconventional interests, or distinctive styles. Quirks often add charm and personality, making people more relatable and memorable. In psychology, quirks can be seen as a reflection of one's individuality and creativity. While some may view them as odd, they can also foster deeper connections with others. Famous figures like Albert Einstein and Steve Jobs are often celebrated for their quirks, which contributed to their innovative thinking and success.
