How many times have you listened to a track you just bought and wished you’d not spent the money, only to realise later that it was brilliant?
The music hasn’t changed but something in your world has made you understand it and connect with it. Maybe it’s just grown on you.
Record everything you do, every single time you stop working. Be militant about this. Make sure you leave enough time at the end of every session to record it, even when it’s completely unfinished, sounds terrible and you hate it. Especially when you hate it.
Because you’ll probably listen to it at some point in the future and realise just how good it is.
