<font color="#000088">I agree with the others, your art is your own,and it takes your own vision to create it. No one else can do it for you. So it is frustrating when it doesn't seem to come out right for you.
But when you are under a lot of stress and pressure,and try to push yourself too hard, you can create a block in your artistic flow. Like "Writers Block"! So you've really got to let yourself just relax,and just put your fingers on the keys,and just let the music flow through you,and as you relax and enjoy playing,the words will just come to you!
I play the piano as well,and I sing,plus I'm a writer in the art of poetry,so I can understand your frustration.I've been there!
Just don't give up,it'll work out,and you'll find the words you're looking for. </font>
