I had a couple of cousins that had routes. Way too much work for what they got. They were mostly afternoon routes, so every day after school, collect, fold and deliver papers 7 days a week. Then you had to find a substitute if you were going on vacation, or had a ballgame or whatever.
Where I lived when I was old enough to do something like that there weren't enough homes nearby to make it worth while. But then by the time I was 12 or 13 there were a few lawns to cut (usually $3 per). Come summer my dad hid his own business so I got drug out with him early in the morning to do yard work or something in the garden center.
