This is why financial literacy is a big thing, there’s a quote saying that it’s not about how much you make or get from your salary that will make you liquid, its about how much you save. This has been my way of reminding myself not to spend beyond my limit, because I’m been through this situation already and I know the stress of spending too much. If you really want to become rich, you should know how to control your finances and stay rich for good.
A big yes for this, financial literacy will take you to a better place and no matter how much money you have its useless if you don’t know how to spend it wisely. Investing is a good thing, but the question is what are you going to do if you already achieve your financial goal? Having a good discipline is very important and we should not forget about this one while we are busy looking for other source of income.
Unfortunately, Financial Literacy hasn't been taught yet in school in some countries( just like in my place), the reason why many people mismanage their money and have wrong spending habits. People just learned about this from entrepreneurs, from businessmen, and we need to move closer to them for the sake of learning. I can't really imagine the wrongdoings in handling our money, we simply think about spending on liabilities, not assets.
