You should also look for signs and coincidences. Then pay attention to them. Pay attention to your dreams (Keep a dream journal). The key to opening up your psychic/spiritual senses is to remain aware and mindful of every moment. Trust your intuition and instincts. Trust your military training. Focus and discipline is an asset in magick just as much as it is in the military.
You’re familar with the sayings, “Keep your head on a swivel,” “Watch your back,” “Open your eyes,” "Watch your six (military term), " etc.
Practice using your physical five senses more and then eventually your psychic/spiritual senses will come online.
I hope this advice helps. More can be found using the search function on this forum.
