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.
As far as you are working, trading, farming, whatever you ate earning should be saved in a continuous manner, it should be a long term savings.
There is no rational on short saving, it makes no meaning except you have stopped working, trading, farming, or whatsoever business you are doing. In fact, as long as you engaged on doing one business or another, saving is important. There are no shortcut to be wealthy, it must be through hardwork which involves risks, determination in my opinion.
