Being without a secure place to sleep is a truly dispiriting experience but homeless folk with vehicles are the royalty of the street world. Speaking from personal experience, life is a thousand percent easier living out of the back of a vehicle than trying to survive without one. For the longer term, a cheap gym membership ensures daily showers and much-needed exercise and social contact. And never eat crap from convenience stores. It’s biologically disastrous and your mood will suffer. Stay on top of your self-administration in all ways: healthy food, exercise, social contact, purposeful progress each day.
