To eliminate complication, I have created a template with channels of the bare minimum used to make a tune.
I can then add from there.
It has helped my work flow quite a bit, because i spend more time thinking about the song and the sounds, rather than spending energy on trivial things (such as naming and organization;important but if every little bit helps, i'll work on optimizing my creation procedure).
From there, you can shape your song how ever you'd like. but at least you have some where to direct yourself than just staring at something completely blank.
It also might help focus the session too.
I don't tend to overcomplicate things during the introductory phase. Generally That's the quickest phase. Where I tend to overcomplicate things is tiny details like the FX and the Ambiences. Those things combined with fills & arrangement take the majority of the track.
This is also an important concept to consider as well. It's not so much over complicating, it's knowing when to start worrying about details and how to transition between "giving a shit and not giving a shit".
I personally have gotten to a point where, i can quickly get the sound i want, and then leave it be. Over several sessions i tend to go over my sounds and fine tune them a little bit more after i have decided on what i want to project (ie end of creating transitioning into mixing). In order to retain song consistency (characterized by individual song), i try to process the sounds i make in the same session/day (if i haven't already called it quits for the time being).
I highly recommend you write down your creative process and list every thing you generally do for each track. Start to end (non mastering or mastering included).
This should help you realize several pathways that you can take to just making channels, and getting sounds moving at a quicker pace. Also, the list isn't so much about details, it's about the idea of the sound that you need to consider as you proceed into the finalizing stage.
TL;DR
create a basic template, analyze your work flow process with a list from start to finish, repeat 1 and 2 until you're comfortable with how you're doing things, keep improving.
