Considerations: (see the article at the link)
Recognize that danger exists (don’t pretend it can’t happen to you).
Carry your firearm with you (on body carry), even when you are at home.
Be aware of your surroundings, both when in public and at home.
Be more careful entering / leaving transitional spaces.
Have a deadbolt or other locking device on your door(s) which is simple and fast to operate.
Obtain and practice empty hand defensive skills for close quarters defense.
Your attitude must be – “I will never give up”.
