Passive income and financial freedom, that's two reasons why people saves much their money.
They thought after working for specific period of time, their investment will grow and able to cover their needs in the future without working. But, the reality as we get older, our responsibility are getting bigger.
When you were young, you only need to fund yourself, after you married, you have to fund your spouse including kids, after you old, you have to fund yourself more than before due to having disease.
I think the scale of responsibility can be adjusted as long as you have a really mature financial plan. We must realize that every decision in life is related to finance. The decision to get married and have children is also part of a financial decision. I agree that investment can make your money continue to grow. A return of $ 600 can be big if you keep letting it go without making a withdrawal. But on the other hand, decisions like getting married and having children will affect your investment. Therefore, it is important for someone who is still pioneering investment with small money to make plans related to getting married and having children. If you have a big dream to get a big passive income from investment, sometimes you have to postpone your other goals such as getting married and having children.
