This is a beautiful sonata, one of my favourites, but not the way you play it.
You can't just bang out Mozart at ƒƒƒ. This sonata is NOT a technical excercise, and you work it as if it is an army drill. Do you feel nothing for Mozart? There is no music in this performance, only fingers pressing down black and white keys, with no insight or thought involved.
What I suggest you do is go find a few decent recordings of this (Zimerman, Perahia, Brendel, Horowitz etc) and listen to them. Over and over and over again. Dont listen to the notes, listen to the music. Feel the music. Piano playing is not just sounds at organised pitches coming out of a block of wood, it involves something called soul. Something called emotion. Wikipedia should be able to define those should you not know what they mean. I am very sure you are not a metal robot, I am very sure you have soul and emotion.. now project it through your fingers.
Good luck,
