I think the key struggle for me as a composer to be the best that I can be has been a struggle to find an original voice. This has become my defining goal. Not to say this is the only goal possible or the only good goal. In past discussions I have participated in, some have suggested that it may not even be a good goal - "seeking newness for newness alone" to paraphrase my critics. Yet I'll stand by seeking newness for newness alone as my approach.
I have many influences, including Gershwin, Chopin, Joplin, the rock band Yes, Miles Davis, and many others. When I first started out as a composer, my music showed these influences, which will be with me forever. In recent years though I have tried to step away from them to some extent. I'm more conscious of when I am being "influenced" by my idols and when I am just imitating them. I want to move on into something more "me." Hope that's a good thing!
p.s. here's one piece I posted on the forum about a year ago that is an attempt for an original voice. Whatever you think of it, I think you'll agree there's no Chopin in it (though I may have had his incomparable sinuous melodies in the back of my mind when writing it) - https://composersforum.ning.com/forum/topics/underground-river-ride
