That's what other people find it hard to understand. Investing your money is a much more profitable approach than simply saving it. Money should be utilized to generate more money, rather than simply being stored away for years without any growth. Failing to make use of your money means you're missing out on potential earnings.
It is going to grow in itself if we invest it to a known investment that we are aware of that will generate us money. But here's the thing, people who are saving probably have thought of investing it.
As with all of these people sharing their stories online, I've come to notice that not everyone can afford to invest. And with that, they are only saving their money so that there's something that they can pull off in times of needs.
For that reason, they can't risk. But I am sure that if they try it a little by little, they'll eventually get to see that they're able to take risk soon but they don't have to force it on themselves.
