I practice whenever I can, which whilst balancing a sporadic work schedule and a new baby it's not as often as I'd like.
I wish I could get to the point when I didn't fancy practicing!
I usually alternate days of practice between bass (anything and everything, including being aboit to do my third grade 8) and piano (currently about to do grade 4).
If I can't practice because I've spare time and I don't have an instrument with me (rare) or its not really possible then I'll do some theory work as I'm about to do grade 6 theory, which I'm really enjoying doing.
As I'm not in a band due to working away so often I find having exams, grades and goals to work towards something that keeps me focused on an end result rathe than just widdling through the same old stuff.
I'm very jealous of you being able to practice as much as you do, I'm sure plenty of teachers an experience players on here will be able to give you advice on how to vary your practice and keep you motivated!
