Will the general rise of everything at the moment, mortgage repayments, rent, electricity and food. What are some extra ways everyone is doing to earn a little bit of extra money?

I do surveys, which I love. Cut back on my electricity usage as much as I can. Groceries I try to cook from scratch as much as I can. Not just to save money, but the joys of not having a gallbladder anymore I need to eat low fat to no fat and healthier.
Groceries I try to stick to buying the necessities with only the occasional treat.
Any loose change I put in a piggy bank and cash in at the bank at the end of the year.
