I'm guessing what you're referring to is a poem by Dylan Thomas titled "Do Not Go Gentle Into That Good Night". The first stanza goes:(posted 9330 days ago)Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, Rage against the dying of the light
If this is what you're thinking of, let me know. If not, I'll need more info about the poem you do have in mind
