In the lifestyle depicted by Philip K. Dick in "A Scanner Darkly," individuals embrace a philosophy of living in the moment, driven by a belief that one should seek happiness now, as life is fleeting. The mantra suggests an urgent pursuit of joy, reflecting a sense of desperation in the face of mortality. However, this pursuit quickly turns bittersweet as the realities of life begin to overshadow the excitement of living for today.

As the story unfolds, the fleeting nature of happiness becomes apparent, revealing a harsh truth that the initial exhilaration often yields to despair. The characters' experiences illustrate a cycle where the chase for immediate fulfillment can lead to deterioration and loss, turning once vibrant moments into mere echoes of joy. Dick's narrative serves as a cautionary tale, suggesting that a hedonistic lifestyle may ultimately result in a struggle against the inevitable decline of both spirit and body.
