Over the years, I realize that as I take care of myself financially, I thought this will make me happier.
Then I realize having wealth is just an enabler for a good life. You might put yourself in a satisfied position.
However, what makes us happy can be elusive.
If you earn less than $36,000/yr in gross income, which means you take home $2,400/mth, putting yourself in a financially better position, such as going for a better job that pays you more would make you happier. Do not estimate the extra cash flow that it can help alleviate some necessary spending in life.
Once you get to a certain state where you have more monetary buffer, what brings you satisfaction, the fulfillment kick is likely not money itself.
It is some kind of growth.
Growth in you as a person will likely give you that fulfillment kick.
The more you realize ......
