Invest your saving in precious metals like gold and silver or digital assets like bitcoin, or it can in some potential stock or it can be in real estate. Invest your money where ever you want. Just do not keep it in a bank. The Bank interest rate is not higher than the inflation. You are losing money not gaining it. The point is to invest even if your saving is negligible.
I don't agree that everybody should have their own business. Not everyone will own a business.
But I agree with everybody investing their savings in something. It doesn't have to be a huge sum of money, but the idea of you having an investment somewhere will motivate you to invest more. Even if a certain investment doesn't work out, that doesn't mean you should stop investing and save. Investing is good. I know people that invested in real estate while they were younger and now that they're old and retired they just rely on their investments for money.
It might not make you a multi-millionaire but it will keep you on your feet when you are no longer able to work.
