Books and guitar

I've just finished reading Confession of a shopaholic. Pretty good, I kinda liked it. And I really need to buy another book.

Come to think of it, do you think I should buy a guitar? I can't play it, yet. And I don't think I would take a course. But I can always ask my friends. And Lintang promised to teach me. But still, it's a waste of money if I'm not that into it. If you have an opinion please tell me
