This is good advice. I would also suggest that if you’re currently paying rent and don’t have a car, but are reasonably certain you won’t be able to pay rent in the future, it’s maybe better to stop paying rent now (or as soon as you can to avoid an eviction) and use that money towards a car instead so you also have somewhere reliable and safe to sleep. A car and a gym membership might not be an ideal living situation but that will allow you to stay clean and presentable and potentially work to save up enough for rent in the future.
