O Captain! My Captain!

Everybody matters and everybody is good at something. And small steps really matter! Go chase after your dreams everybody!

“O Captain! My Captain!” is a famous elegy by Walt Whitman 

The scene is taken from "Dead Poets Society" where the students tribute to their teacher Mr. Keating (Robin Williams) who taught them think different, to seize the day (carpe diem) and to stand up for what is right.
