Hey there, welcome to the boards. Lots of information you could take from here even if you live in an apartment. Do you pay for utilities or is your apartment rent all bundled? If you do pay for utilities then there's probably a lot of things you could do around the apartment to help you save money (unless of course you already do them
).
Do you have a balcony? If so, do you face the south sun? If you do, there may be some gardening you could try out...even if it's just in one or 2 pots. A few fresh tomatoes in the summer/fall are always good to have. Or you could even play around with solar paneling if that peaks your interest. And then once you've mastered solar paneling you can teach me.
Good to have you here!
