I Have My Passport. Now What?

So about a week ago I came home to find two envelopes in my spot at the table, one with my old passport in it and one with my new passport in it. Normally this should take 4-6 weeks but mine only took about 3 weeks, so that's pretty impressive considering this is a government thing.

I opened up the envelopes and the contents of the envelopes looked like this.

The one on the left is my new passport and the one on the right with the holes punched in it is my old passport.

First things first if you are over 16, SIGN YOUR PASSPORT!!! I'm going to do that right now, actually. Just have to find a pen that works...

Now my passport is signed and something I have noticed before is that my old passport is not signed! I was 13 when I got it so that is under the age where you have to sign it yourself but I guess we just never signed it? That passport was used to drive across the Canadian border multiple times and we never had a problem so I have no idea what the deal is. This is my third passport by the way and my first one was signed by my mom because I was very young when I got it and couldn't really write that well.

Anyway, let's move on to all those papers that came with the passports. Two of the pieces of paper are just "if you applied for this, you will receive this in the mail," one is a pamphlet about general passport care and international travel tips, and the last one is information about TSA Pre and similar programs. General passport care is sign your passport, report immediately if stolen, carry a photocopy of your passport and visa with you at all times, and keep the contact info for your embassy with you. The TSA Pre and other Trusted Traveler Programs paper outlines the various types of programs, which are for travel within the US, between the US and Canada, the US and Mexico, and the US and other countries. All are fairly similar in price and application process so basically just pick whatever works best for you if you want to do something like that. I often get selected for TSA Pre anyway being under 18 and all so I can confirm that it is really nice and if I get it and other people in my family don't I will often take some of their luggage like laptops and liquids and such with me simply because it's easier to check through the TSA Pre line. While I do like TSA Pre and my parents are considering getting it for my sister and I, I do not plan on getting the international version for my trip to Japan because I feel it will be easier to follow the masses then to try to maneuver a path that is perhaps a little more convenient.
