The soldier takes pride in saluting his Captain,
The devotee proffers a knee to his Lord,
Some back a mare thrown from a thoroughbred,
Troy backed its Helen, Troy died and adored;
Great nations blossom above,
A slave bows down to a slave.
Those who suffer from an exaggerated sense of their own ability and accomplishment are continually subject to frustration, disappointment, and rage when reality intrudes and the world doesn't validate their idealized view of themselves.
I thought of Chatterton, the marvellous boy, The sleepless soul that perished in his pride; Of him who walked in glory and in joy, Following his plough, along the mountain-side. By our own spirits we are deified; We Poets in our youth begin in gladness, But thereof come in the end despondency and madness.
