Sometimes in retrospect, you'll realize why your gut was sending you those signals. On the other hand, some things that seem unsafe to a beginner are actually safe (don't ask for an example, because I can't think of one right now, but I know that has also happened to me), but in general I don't think you can go too far wrong by trusting your instincts.
