Hrm...when it comes to prioritizing, here are the things that I love equally: Writing (which includes writing games for D&D), Reading, Music (in all aspects), Dagorhir. With just those alone it's impossible to have enough time to do them all.
A lot of people narrow down to one or two hobbies once they get older. Now I see why.
It's true though, that the internet sucks away your life one click at a time...but damn it's addicting.
I have no idea how people manage to fit in more than 2 hobbies. I'm constantly promising myself, "I'll do this tomorrow", "I'll spend more time on this on the weekend", etc. AND those things never happen. Life gets in the way.
