My practise time varies considerably. But recently it's been rather spasmodic to say the least. 30 min one day, nothing the next, sort of thing.
I'm sort of going through a bit of a phase at the moment. This time last year I was a big advocate of practise, practise, practise. But the last 3 months has been a bit of a downward
slide for me emotionally which has taken it's toll on my playing enjoyment.
