A poem I found:

Mother to Son
Well, son, I'll tell you:
Life for me ain't been no crystal stair.
Its had tacks in it,
And splinters,
And boards torn up,
And places with no carpet on the floor---
Bare.
But all the time
I'se been a-climbin' on,
And reachin' landin's,
And turnin' corners
And sometimes goin' in the dark
Where there ain't been no light.
So boy, don't you turn back.
Don't you set down on the steps
"Cause you finds it's kinder hard.
Don't you fall now---
For I'se still goin', honey,
I'se still climbin',
And life for me ain't been no crystal stair
By Langston Hughes
