If you have the time I would like you to read “The Gift of Fear” by Gavin De Becker.
I may seem off topic. After you read it you should see it’s importance in what you do. Obviously there are times you won’t be sure what you’re getting yourself into. You want to be prepared to handle yourself to the best of your ability. Having a little fear is a good thing. Having no fear is dangerous.
If you like a good psychological read you will enjoy it.
