Nope, and I am poor too was poorer in the past.
I did a envelope thing. Once I account for my bills I divide up the remainder (yes, I used cash for this) and place a amount I get per day in one of 30/31/28 envelopes. So I would need to save up a few envelopes if I needed new shoes.
It was hard but It made it so I always had at least I had a new envelope with 20 bucks a day to open.
When I was a teen my mom got survivors benefits. We would get about 1,900 on the third of the month. It was gone in a week so we had to do less then legal things for food for the rest of the month. We should have been fine on that amount for the entire month. She just got off on shopping and eventually found herself into the pawn-shop trap. My Super-Nintendo spent more time on a shelf then it did with me. But every month she would pull it out of pawn only to be put back in a week later. She got 25 bucks for it and it took 50 to get it out.
Ramble, Ramble.
But yeah. I would use daily envelopes so I would always have money on the day before I was paid.
