ok -you've got a gym membership and a car but can't afford housing
it seems you've gone about this sideways
Planet Fitness is like 10 to 20 bucks a month. All you need is dollar store soap, some shampoo, and towels.
There's this used car lot down the street from me, has been there for years. Painted on the side of the building is their slogan..."If You Have a Car, You Can Get a Job"
Of course it depends on where you live, but many times it can take you an hour or more to get from your home to where you work. Then, all day long you are stuck there. Reverse that going home, and now you've got to figure out how to carry enough good food home, plus get anywhere.
To me, when in dire straights, having a car, and a gym membership is infinately more useful that 4 walls.
Back in 1989, my first short marriage, things got really bad financially. We did have our house, and could pay the mortgage, but I had to literally budget $7 a day to cover all our food, sundries, and my gasoline.
The way I accomplished it was that the gym I had belonged to in another state was 2 miles from my house. A grocery store was accross the street. The annual renewal fee for the gym was $69.00. It was a Bally's
Every day I would drive to the gym, then afterwards walk across the street, buy whatever fruit, vegs, bread, bulger that was just for that day. I'd put whatever change aside and that was gas money and some meat. We were both very healthy that 2 or 3 months period. I went from some marginal part time job to full time somewhere else, things got better, and I knew I could have gone on that way much longer.
If you have a car, you can get to where you need to go, and don't have to be dependant on where public transportation can take you. Then, once you have a job, and some money, you can get a place close by.
Most importantly, there's that knowledge that if your careful and do the right thing, you can totally take care of yourself.
