Chimamanda Ngozi Adichie said this quote

It was what Aunty Ifeoma did to my cousins, I realized then, setting higher and higher jumps for them in the way she talked to them, in what she expected of them. She did it all the time believing they would scale the rod. And they did. It was different for Jaja and me. We did not scale the rod because we believed we could, we scaled it because we were terrified that we couldn't.
