I have never heard so much self-absorbed, holier-than-thou, judgmental piety! Blah, blah, blah...transparent phrasing...blah, blah, blah...super legato continuative sound...blah, blah, blah...contrast between dynamics...blah, blah, blah, blah, blah.
You will find that the hardest thing about learning any piece, Mozart or otherwise, is listening to puffed up players tell you how it SHOULD be played.
Sit down at your piano, learn the piece note by note in as much time as it takes to do so, listen to as many interpretations of it as you can so you can find your own unique interpretation, and be true to the way the piece evokes emotion from within YOU and try to get that message across when you play it for others. Take as much time as you need to play it as beautifully as YOU will play it when you pour yourself into each note. Don't let anyone tell you it should be done this way or that. Don't let anyone tell you that you don't play as beautifully because you don't do this or that. Just let yourself experience the joy and let that joy flow through to your craft of playing. Have fun and share it with others by playing with integrity and love of the art.
The only wrong way is the way that will cause pain or injury so pay attention to technique insofar as it keeps you from injury and allows you to play with ease and efficiency.
