Good luck! I thought this was going to be about FAWM when I saw the title, but FAWM’s more about writing than production, though many take it as both. 
I did a bunch of these sorts of things in previous years, and then found myself going idle for months in between. For me, committing to at least one song a week wound up working a lot better for getting the flow going, and now I’ve worked up to where it just comes easily and consistently. But I expect there was probably something helpful in doing these sorts of challenges too.
