What is the figurative language of the poem: examples:

Well, son, I’ll tell you:
Life for me ain’t been no crystal stair.
It’s 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 those steps
‘Cause you find 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.
