The most helpful stuff I got wasn't from MMM. There are some great concepts here, but MMM is a married man in a stable career, and it shows in his blog posts. Trying to go it alone on an income below the poverty line isn't something he has a lot of experience with.
I spent 10 years working min wage, in and out of school, working multiple jobs per year while dealing with chronic illness. I found The Simple Dollar to be very helpful.

Read between the lines - if the author assumes that you live with your parents while you're at school, or that you're in good health, or that you don't have kids, or whatever, that particular author may not have the best advice for you.
What Color is Your Parachute is a classic for a reason. I have the 2007 edition, which was all about acing interviews and and sidestepping up the career ladder. He rewrites it every year, it'll definitely be worth checking out from your local library or stealing a pdf.

It's about how to nail everyday conversations and stand out from the crowd of people vying for your dream job. It helped me learn to leave a good impression with everyone I worked with, so that I was the first person who came to mind when employers were looking.
https://www.amazon.com/Land-Your-Dream-Career-College/dp/1442219467The one piece of advice I wish someone had told me: start with the cheapest, easiest way to get the job done, and adjust later. I used to spend a lot of time wondering "should I buy meat this week with my groceries? Should I buy canned beans, or make a special trip to the store where I know they have cheap dried beans?" It's hard to decide where to spend your time and money when you never have enough of either. Also, I changed jobs seasonally, and was in and out of school, so what I needed one year was very different from what I needed the next year. I learned that if I bought dried beans I would never actually eat them, but canned beans were easy to use up. I learned to slow cook soups and prepare freezer foods. I learned that if I was working 16+ hours in a day, I'd be living on ensure and ramen noodles because I'd forget to turn on the slow cooker before I went to bed.
As long as you don't stop, you're doing it right. I promise. Best of luck.
