One of my favourite hobby is doing new stuff. I have so many new stuff on my hand which I didn't have the chance to finish them completely. Take for instant I first start with learning hangul, then horoscope, tarot cards, fengshui, baking, cooking, travelling, self development, management skills and many many more. Learning new things can widen your knowledge and mind. No wonder Sagittarius have lot of knowledge, cause they love to discover new things.
