Here's what my experience tells me. We have 3 AA meetings a week in the small town where I live.
When the stinking thinking starts in and maybe I'll take a night off and not go, or I have a headache, or there's a tv program I like to watch, I look at what I have on a sticky note beside my computer.
1 day = 24 hours
7 days = 1 week = 168 hours
1 meeting = 1 hour of my time (approximately)
3 meetings per week = 3 hours of my time
If I attend all 3 meetings that week, that still leaves me 165 hours to take a night off, have a headache, or watch a tv show I like!
