> I read a book that said you should try something new to you at least every quarter if not more often. It gives you something to talk about.

not OP and not sure of the book but if you're interested in material like this, check out Derek Sivers' work - usually revolves around stepping outside your comfort zone, exploring new ideas, etc.
