The essence of life, as described by Kundera, emphasizes the unpredictability of our choices. There’s no definitive way to judge which decisions are right or wrong because our experiences come without preparation, similar to an unprepared actor facing the stage. This lack of a rehearsal means that we must navigate through life without any established guidelines, making each moment unpredictable and unique.

Kundera further illustrates that life resembles not a well-defined picture but an incomplete and aimless sketch. Unlike sketches that serve as blueprints for a finished work, our existence lacks a predetermined endpoint or a clear vision. This analogy highlights the transient nature of our experiences and decisions, underscoring the notion that life itself is an ongoing process without a final resolution.
