Nothing very specific, just some general thoughts.
Sooner or later you have to realise that less is actually more. I used to fill up my tracks with many layers, every gap had to have plenty of content. But when you reach your mixing stage you start to realise how flawed this idea is in general. if you mute some track and you can’t here any difference in the mix it should stay muted or at least somehow used in other context. You can achieve a complex general sound but that doesn’t mean you need to layer over 20 different audio tracks and take extreme surgical measures to merge them all together. It’s not worth it. Some room needs to exist that could nicely wrap up and highlight your sound design decisions.
While trying to fix that one sound for hours sometimes it’s even better to re-do or replace it completely. Don’t be afraid so scrap that one idea that you’re trying to get “right”. It’s very tiresome. Save a backup project and instead try something different for that part.
When you reach the end of the line with some work in progress where you have no idea how to continue with it, start a new project. Select same BPM and key (let’s say that previous project had sub bass layer in F0) so you can use that as a reference and start building stuff from scratch while not even trying to match that previous project too much. Then you can quite easily merge projects and copy/paste layers from each other, merge ideas, borrow stuff from one WIP to another because you will have more stuff to choose from (“these layers might fit in that other WIP i worked on!”). I name projects like 170_s_01… 170 is bpm, S means I focus on some sort of synthesis, etc… This works surprisingly well for me.
