The author Milan Kundera, in "The Unbearable Lightness of Being," suggests that while individual differences among people are vast, there are underlying desires that unify them into categories, particularly in relation to their lifelong pursuits. This perspective implies that these deep-seated motivations play a more significant role in shaping people's identities than surface-level distinctions. By focusing on the fundamental desires, one can better understand the choices people make throughout their lives.

Kundera's observation about actors highlights this idea—despite their unique backgrounds and personalities, they share common traits rooted in their passion for performance. This reinforces the notion that certain professions attract individuals with similar deep motivations, further demonstrating how desires can serve as a unifying force among people, transcending individual differences.
