I don’t have kids so my views might not mean much but my work and my other interests take up most of my time.
For me to make music I employ the following… if I don’t do this then I can go ages with out making stuff… in summary I remove all barriers that may prevent me wanting to make music - I find the depression of this comes from when you don’t make music, feel guilty, think you’ll pack it in etc so I make sure that doesn’t happen.
1.) only have gear that doesn’t impose on the room they are in - room still looks neat n tidy and can still be used for other things/hobbies/interests (so you keep coming back into the room often for various reasons, not just for music, doing so it keeps you looking at your instruments - lost time how many times I’ve gone into studio for something else and then just decided to make music)
2.) keep everything wired up. If I was to put anything away or not have it setup up with just power switch needed to make it work, it would then need even more time, more effort, more desire to set it all up. Therefore if stuff was boxed up or packed away I’d go months never playing them, too long you get rusty, being rusty makes you even less likely to pick the gear up as you know you’ll be longing to be as good as you used to be.
3.) when I do go to play, whether it’s my guitars or groveboxes, I always give myself an hour. I set a timer. 30mins to make up a track or riffs of song on a looper. Then I use 30mins to do various takes of the performance, I never program much just mute/unmute throw in effects as n when etc, then I just save the best take. Upload track. Delete recordings, never return. You end up with hundreds n thousands of tracks over the years, I always enjoy listening to them and it keeps making you want to do it again.
4.) I almost always never start from scratch, just always take last set of sounds and tweak them from there. I’ll only start from scratch if I know I’ve a whole day to myself. If I start from scratch I find inspiration harder to come by, if I take my last set of sounds, I’ll get new idea nearly straight away and then start tweaking then I’m sucked in.
I’ve done the above since the day I first picked up a guitar 24years ago and I’ve nearly a recording saved for every single week since. The only times I’ve ever put music down for periods and been down on it has been when I’ve moved house, gear packed away, need lots of free time to get it all setup, get your touch back etc so you keep putting it off n off n off etc.
