What does the phrase "If I put my mind to it, I could write like Shakespeare" exemplify?

The phrase "If I put my mind to it, I could write like Shakespeare" exemplifies overconfidence in abilities. This assertion implies a belief that with enough effort or determination, one could achieve a level of skill comparable to that of a literary genius like Shakespeare, which is often viewed as an unrealistic expectation. The comparison highlights an inflated sense of one's own potential, especially in the context of writing, where Shakespeare’s mastery and unique voice are recognized as incredibly challenging to replicate. This indicates a misunderstanding of the talent, experience, and artistry required to reach such a high standard, reflecting a degree of overconfidence in one's own creative capabilities.
