What I’ve learned is long practice sessions don’t really work for me, I don’t tend to absorb it all, whereas if I do 1 - 2 hours I remember everything, also if I can’t quite get something like a tricky Bassline, I always take a break then come back to it , and more often than not I get it straight away , I used to end up noodling for hours but now I make notes of what to focus on
