What things are pillars to maintain an optimal state of well-being?
Happiness in life, and a proper amount of income, and a proper and stable access to a food, water, and a warm place, where you can stay and sleep. I have the first, but not the second, and sometimes only partially the third and the fourth. My total income (approximately $470 USD per month) is less than the local minimum wage (approximately $550 USD per month).
Have a nice day. All the best. Greetings from Hungary.
