Not a poorfag but I live like one to survive.
If you aren't a fag about your personal data, monetize it. Honey, Ebates, Ibotta, etc. have some really good deals for
Qmee is the best "earn money for taking surveys" app because you can cash out at any time, most require a $10 minimum.
Flipping thrift store finds is a solid option if you're targeting a niche. I've made a few grand off of people looking for Power Rangers toys alone. You can look for toys, clothing (relist on secondhand sites), housewares, furniture, etc.
People go crazy for dressers and nightstands especially.
Socialize with neighbors and find out if there's something they need. I make $50 a month off of giving one neighbor space to park his work vehicle on my property since the city has a street parking ordinance in place because street parking fucks up the snow plows.
One time gigs too. City hall tends to have information on quick opportunities like that to make money if it isn't the city outright asking for it.
Know your area's services for those struggling as well. Local gov has been giving gas cards to people but it's one of those situations where you have to ask directly, there isn't any signage and it's by word of mouth.
Unclaimed properties as well. Search your name, your family's names, deceased relatives. See what you can find.
My biggest advice for people who are struggling is to go places and talk to the people. Digital communications take away the human element and sometimes just showing up somewhere can net you something good.
Also, I hate reddit but r/beermoney is pretty solid for fast ways to make money. That's where I learned about qmee.
