There's a renowned Brazilian producer and tutor that made a challenge of 30 songs in a month, and some of his tips after he finished was:
* Create a basic template of the things that you use most, sends of reverb, delay, a sidechain channel etc.
* Don't limite yourself of create timbres from scratch, you can use presets, tweak them a bit.
* Midi Samples you can easily find in the internet (Bass, leads) and is very useful for a quick inspiration
* Preferably disconnect yourself from internet, forget to check email, notifications, etc, you may be surprised with two hours of your focused work.
* When you're producing the track, loop your arrangement to 16-32 beats, to mentalize some elements and variations that can appear in the next 16-32 beats
* The same happens to mixing, loop your arrangement to 16-32 beats and you will preview your track very fast, after some of this loops you'll start find unwanted frequencies.
* Mute some channels when you're listening your arragement, maybe you can find some parts messing your music, (remember in general music, less is more) also lack or excess of some frequencies in the individual channel tracks.
