Earning money is hard, saving money is damn hard, getting rich and being able to live comfortably is insane.
For me saving just for short term, you can't earn anything and your wealth will decrease over time. People have to take big risk if they want to be rich, if they only take some risk or little risk, it's not enough.
What does big risk mean? it's a risk where you can lost all of the money you invest e.g. start a business, invest in new thing etc.
