The primary theme of the text is resilience, perseverance, and overcoming adversity. This is strongly suggested by the title 'Never Give Up!' and the stories of both Bethany Hamilton and Tom Conaway.
Bethany's story showcases her determination to surf again after a life-altering shark attack, while Tom's story highlights his positive attitude and ability to pursue his passion for filmmaking despite a severe physical disability. Both individuals exemplify the idea that challenges, no matter how significant, can be overcome with courage and a refusal to surrender.
