During some harder times I tried to survive solely by collecting bottles and cans since I had often made some extra pocket money by picking those up aggressively. Turned out that it's not sustainable at all and I found it to be impossible to pay the rent that way despite living in a large city and tourist destination. Unfortunately I was also too autistic/self-conscious for busking or panhandling.
