I think it is true. I've certainly gotten more attracted to my own music over the years.
Yeah, I agree with that, and writing a masterpiece has never been a goal for me. Even when I think of writing a symphony or a concerto as goals, which they have been, I never think of them like they are masterpieces. They may very well turn out that way, but I don't think about whether they will or not, I just compose what I want to compose.
I just approach my own music like it's just another piece. I don't think anything special about it in any way, even if it's written for an uncommon ensemble. My process often starts with me improvising a little idea or 2 at the piano. Then I think about whether I want it to be piano solo or for a different ensemble. Once I have that and the key figured out(the key is usually figured out with the improvisation itself, if I improvise an idea in C minor, I generally stick with C minor as the key of the piece for instance), I then write the piece, developing as I go. Take the C minor fantasia I'm currently composing for instance. It started off as an improvisation in C minor where I was cycling back and forth between 2 main ideas, a slow, legato idea that gains melodic momentum with each repetition and a fast, almost march-like, staccato idea. I then thought of expanding it out into a trio, so I did that, and my initial improvisation became the piano part of said trio.
I do listen to my music a lot, about as often as I listen to pieces by other composers. I've never found my listening to be too much, it's never prevented me from having new ideas. It has however sometimes stopped the writing of one particular piece in its tracks before, especially early on as a composer in what I call my "Year of Ambition" where I was trying anything and everything that crossed my mind to compose. And when I look back at it, there are definitely pieces that I stopped before I got much further for one reason or another. Like my second piano sonata, stopped because of a K 545 resemblance. K 545 haunted me as a composer from when I was 12 and basically wrote a structural duplicate of K 545 in Bb major as what I would now call my Piano Sonata no. 0 all the way up until Mozart's birthday in 2019 when I finished writing my Piano Sonata no. 4 for which I purposefully borrowed from Mozart. Every time I'd try to write a sonata between those, I'd always be like "Damn it, K 545 hit me again, better stop before I get much further in this", not because I hated K 545, I don't, but rather, I just felt that it was a sign that I needed to study more sonatas rather than just listening to them, as at the time I wrote my Piano Sonata no. 4, K 545 was still the only sonata I really seriously studied.
Or my String Quartet no. 1 that doesn't exist anymore because of the update issue on my old computer that made me lose a bunch of my scores, I stopped that because I just felt the string quartet was too hard. I still feel like it's incredibly hard. And indeed, sheer difficulty is one thing that even today will stop me in my tracks sometimes, it's why I have no string quartet pieces that I'd title String Quartet no. 1(at least not anymore), and it's why I have no finished fugues even with all my counterpoint and fugue studies over the years.
But listening to my own works has never prevented me from having ideas for new compositions. If anything, it's encouraged it. I get so many ideas for compositions, that a lot of them end up being left unfinished without the intent of leaving them unfinished.
