Here's my safety trick....
How many times have you read an accident or incident report and thought, "gee, that was really dumb" or "what were they thinking." Well I use that to my advantage.
When I have to make a tough go/no go decision I imagine anything that could possibly go wrong and if I can imagine an accident investigator thinking "gee, that was really dumb" then I won't do it.
Thankfully, I don't have use this too much anymore, but it kept me alive for a couple of years in the wild, wild north (Canada = 3000' gravel strips, no wx info, an ndb if you're lucky, sometimes flare pots 'cause there are no runway lights).
