There's a lot to say about being a letter carrier. You're outside all day, pretty independently; there are days where you're really going to love it. There will also be days where you're gritting your teeth just imagining working anywhere else. If you don't mind working somewhere close to 50 hours a week, sometimes 60 when you're new-- well, you'll be just fine. You'll fall sound asleep within 5 minutes of your head hitting the pillow just about every night. Not for everyone, but it has its perks.
Nice way to stay in shape, an honest living
Short lunches, huge time commitment
