Yeah, I couldn’t live on that now. But I was 19 years old, 116 lbs and in great shape. Bicylced from my off-campus apartment to classes every day. I ate some rice and beans also - cheap. I remember eating an avocado with soy sauce and sour cream - they must not have been so expensive like they are now or maybe I splurged since I didn’t have them very often.
But I always took my calculator to the store to make sure I didn’t go over my budget. I worked full time every other semester in a co-op program so all that I saved had to last the entire semester. I even read my electric meter every few days to make sure my electric bill wouldn’t cut into my food budget. Don’t miss those days!

it is key to also put every penny into YOU cause YOU is all ya got, ya know what I mean?
…ugh…I hear you loud and clear but truly any time you put into you is a good thing tho
