Where is quixotic origin?

The term "quixotic" originates from the character Don Quixote, the protagonist of Miguel de Cervantes' early 17th-century novel "Don Quixote." The character embodies idealism and impracticality, as he embarks on misguided adventures in pursuit of chivalric ideals. The Word has since come to describe someone who is exceedingly idealistic or romantic in a way that is unrealistic or impractical.
