Bills/expenses are important in the following order:
- Rent / roof over your head
- Electricity and gas
- Food (fresh food, frozen food, canned food. This is also the order of the speed this food goes bad with fresh going off first and canned lasting the longest. This can also be the order of nutritiousness with fresh being the best. The reverse on cost with fresh usually being the most expensive).
Saving money is more important than moving out unless employment prospects are nil back home or it's psychologically taxing to be around family. That saved money, whether using retirement options via employers who may match your contribution or through your own individual bank or brokerage, provides freedom to move out with more choices, or travel, or quit a sucky job, or deal with an emergency etc.
I didn't understand this for a long time myself. And I can't rightly remember when I first learned about this sort of thing. But once I did, information just seemed to flow to me from multiple directions. Maybe look up classic tactics around sales and marketing, then deceptive, yet typical, psychological sales and marketing practices. There's a book on credit cards I enjoyed years ago "How to Take Advantage of the People Who Are Trying to Take Advantage of You: 50 Ways to Capitalize on the System" by JSB Morse (Though long story short, avoid debt and credit cards). One video on YouTube turned me off of buying ink cartridges once I found out what they truly cost versus the exorbitant amount they sell them for. Capital rip offs.
