If you're a regular publisher and actually do 8 hours 15 mins, then you round up to 12 hours.
Doing 130 hours a month isn't as hard as it sounds, if you count your time flexibly.
Leave house at 8:30, put a leaflet through a neighbours door and pioneer stroll to your favourite cafe. Have coffee ostentatiously reading a WT or AWAKE! and then leave the set of mags at the coffee house when you're done. (Count 2 mag placements, & 1 RV)
Pioneer stroll to the meeting for field service at 10:00 , count your time since you probably lead it. Spend ages making sure people have territory / partners etc.
Do an hour's first call, then head to different coffee shop. Make that last til lunch. After lunch, wander round your territory calling at empty homes & posting magazines, count as return visits.
By this time it's probably 3:30 & you can pick up the 'young one' from school whose parents need help studying with their kids. Take them home and fling on a JW DVD.
If you're lucky the family will offer you dinner. Stay til 6:30.
8:30 - 6:30, you've never been off the clock, you placed 12 mags, did 6 RVs and one bible study. 10 hours.
Do this 3 times a week & you can even have weekends off.
