Well, not to be contraversial, but you could also try living life without a 'threat model' assessment to live by. That sounds very close to living in fear, and that sounds miserable.
This "threat model" assessment doesn't come into play if your habit is to have it with you at all times. It's like how you have your wallet with you so you don't fear not being able to afford a trip home; you only really start having to assess these threats when you don't have your phone/wallet with you. The phone and wallet is thusly liberating you from such fear.
