This poem is a dramatic monologue spoken by a mother to her son, using the metaphor of climbing a stairway to represent life's journey. The mother warns her son that unlike the smooth path implied by a "crystal stair," life will present many obstacles in the form of "tacks" and "splinters." However, she advises perseverance, as her own struggles show that steady progress is possible through endurance and faith. The mother aims to prepare her son for the challenges of being black in America by sharing her hard-won wisdom about maintaining hope in the face of discrimination and poverty.
