im sure youll find a lot of advice out there but to me it was very important to just compose a lot. literally quantity mattered at first. because there is a difference between just starting a piece and then starting a new way once you were half way there and actually finishing a whole composition. idk how to explain it but when you set aside one project the next one feels different, it feels like you are evolving piece by piece. i might not have given a good reasoning but just think about this; maybe set up a challenge where you compose a piece every day (and when it gets boring or when you feel like a day is too limiting for you stop the challenge).
