Particle physicist, Dr. Lawrence Krauss emphasizes the unlikeliness of human existence in the vast universe, and urges a sense of gratitude and appreciation for the mere fact of existing and the ability to understand the universe and manipulate it.
The search for meaning and the act of searching for something more meaningful is life's meaning in itself, as humans spend such a tiny minority of its time feeding and have an enormous cognitive capability that can be used for all kinds of other things like art and exploring different aspects that are not directly tied to a purpose.
Having the belief that one has control over their life and the ability to take action can lead to increased motivation, drive, and resilience.

The Buddhist phrase of setting the impossible goal of freeing all beings from suffering can serve as a nice aspiration for living a purposeful life. By making everything you do useful to other living beings, you can feel fulfilled and inspired to be the best version of yourself, like the one-legged African-American ski racer from San Diego.
The question of the meaning of life is an open one, but simply asking the question can be a valuable exercise. For some, considering this question may bring joy, while for others, it may not matter much at all.
