I often hear from my elders that those who work hard, suffer and work patiently today have a very happy future. So I think that instead of increasing the standard of living today, it should be used for saving and investing. So that we can ensure a beautiful future. So my personal opinion is to invest. Because if you want to do something productive in life, you must invest. There is no other honest means or way to grow in life except investment.
Ignore advice from elders, the world is very different now than it was 20 years ago not to mention the difference in longer time spans. Advice that worked before does not work today. Generally just saving money is terrible. There was a time when this was the best thing you could do, but now it is one of the biggest mistakes you could make. Saving to invest is something else, but usually when someone talks about saving it refers to the traditional stacking of money in a back account.
