I know this sounds harsh, and the examples I provide are kinda extreme as well, but I think this might help a lot of people.
A lot of people complain about rent. A few weeks in the homeless shelter will save you a lot of money, and you only really need housing in winter. It's also not always necessary to buy food yourself. There are many ways to obtain food without buying it, such as trashcans of restaurants. It's also good to note that dog food is often cheaper than normal food and contains at least as much nutrients.
I hope this was helpful to some of you, and good luck out there!
