ANDY'S ANSWER: There is nothing you can do to speed up puberty. Every person has their own individual timer that nature has picked out for them. You're just going to have to be patient and wait for it to happen like everyone else. Lots of people miss the first signs of puberty because they aren't paying attention. Why not keep a diary of your body changes as they happen and document your puberty? The information will be fascinating to your children later when you become a parent, and it will also make you more aware of the changes as they happen to your body.
