It totally depends on what you can do and what your interests are.

Isn't the point of downsizing so you don't need a side hustle?

Try one of the placement agencies?

Don't have no clue what you mean but one of the best ways over the year to save a hole lot of money is meal planning and then when you use rice noodles and instant potatoes with most all meals and buy them large bags of cereal and I can cover my year cost of that just by picking every pop bottle up I see and it adds up to hundreds and your not eating other unhealthy things because of not being hungry a hole lot and this is from a state worker sitting with me and doing planning.

What qualifications do you possess? What education do you have? If none, you'll find that LOTS of people will recruit you to sell various types of ****. There's no money in it, though.
