I agree with a lot of the things Jennifer mentioned above and the bit Nicole mentioned in the initial thread.
There are so many variables so I'll try to stay as generic as possible.
It's mostly just the two big elephants in the room;
Work More to Make More than just enough (find a side hustle) orFind a new living situation that allows for current income to be more than enough (e.g. https://www.cheaprvliving.com/).
Oh and the third little baby elephant which is maintaining the frugal lifestyle to put any extra to savings.
In that case, I think building social capital is most valuable in this situation. It should not cost any money and It can do two things, Increase the potential income and/or offer a better a living situation.
Most importantly; build it with people you would like to emulate.
Find someone in your area, or Join a group of people, that is doing something you love and talk with them.
e.g. If you want to start a side business, find a group in your area that is doing/learning/teaching how to start a side business. (These are absolutely available, for free, in every medium/large city via something like meetup.com)
You may find something/someone that allows you to increase your income or an awesome new flatmate or a farm owner that needs someone to watch their farm in return for a place to live.
Keep those thoughts positive and things will move in the right direction.
