The clip comes from X-Men: Days of Future Past, the 2014 film where the X-Men send Wolverine back in time to prevent a dark future for mutants. Hope is the central theme of the story, summed up in Professor X's message to his younger self about enduring pain without losing hope. Clips from the film became popular in fan edits and motivational posts online, and this short excerpt spread on soundboards because it captures that theme in a few seconds without needing the full scene for context.
