Very well put. If you mean that you'll be on 3 connecting flights, you likely will not leave the secure area in the airports (unless your connections are like a day apart). You will be given all 3 boarding passes when you arrive at the first airport, so you just need to keep track of them to check your flight info. Also, your checked baggage will be moved from plane to plane for you, so the only thing you need to do between your home airport and destination airport is make sure you, your carry-on bag, and your boarding pass are on the right plane at the right time.
