gliding is not dangerous, but it can be highly unforgiving.

Every decision should be a consious one.

"Is it safe to fly in that direction?"

"should I fly with a audio vario or flarm?"

"did I do a good preflight check?"

Sometimes when I am confrontated with a difficult decision , I pretend that I ask my girlfriend ( flies too) would do. That it itself is already a reason to look for other options.
I also found that it is often not the super pilot that takes the most chances , but more the sub-top "wanna-be's ".
