Imperfections and disabilities.

"[No] for God selected (deliberately chose) what in the world is foolish to put the wise to shame, and what the world calls weak to put the strong to shame... what in the world is lowborn and insignificant and branded and treated with contempt ... that He might depose and bring to nothing the things that are. So that no mortal man should [have pretense for glorying and] boast in the presence of God." 1 Corinthians 27-29

Your imperfections and disabilities are all reasons to praise God all the more.  The more you have, (and we all have so many), the more the world can witness God glorifying Himself through you, leaving no mortal man, no matter who they think they are, the ability deny the power of Him who lives in, and through, you.
