The go/no-go decision isn't always obvious

Pilots constantly do battle with the question of whether to push off into the gray unknown. But it's not the only time we've beat ourselves up because we can't decide whether to go flying. What about the time we got out to the airport and the wind was higher than we like? Or the time we nearly dozed off while driving to the flight school? How about the day we had the big blowout with the spouse and we decided to go flying because we were so distracted that we were useless around the office? Was it smart to go aviating?
