I was about to open a similar thread. Too much hobbies, too little time.
I don't want to abandon any of them, they're all precious to me. Too bad I don't get paid for doing them.
It's only spare time management. You could spend the minimum necessary time that you can improve at each particular hobby.
Some hobbies require daily practice for 1 hour, others once a week. Some mean reading books, articles, forums on the internet. It's not wasted time! Just don't forget tot enjoy your free time, for that's the point of hobbies.
Edit: ssandra, thanks, I have read the article and it applies to me.
