While defensive tactics and firearm proficiency are important components of personal protection,  ADAPTABILITY  is the key to survival ​—​ always be prepared to improvise!  If you plan to do something one way, make sure you can do it a different way.  If you are skilled at performing a task right-handed, be well-versed at doing it left-handed.  Anything that you are able to do 'standing up' at the shooting range, be able to do it sitting, kneeling, prone, and supine with either arm secured behind your back. Basic capabilities such as these can make all the difference in an unforeseeable or unpredictable situation.  Get good at doing basics ​—​ basics win fights!
