Look, you can be old and rich or young an poor, but being old and poor is bad shit.
A surefire way of doing the wrong kind of things is to spend your money early or try to live a good life quickly without thinking about the future. Or if you have an ok job or income to think that is enough, even if you cannot save.
All young people, understand that time an money are linked. It is not the same to invest early than late, it is not the same to invest more early that try to invest more later. 100 is worth 100 today, but 800 in 20 years if you play it safe but well. Make no mistake, you will need to start creating your wealth.
Saving while young is a good starting point, in the sense that your net worth is positive instead of in debt, but really once you've acquired a decent backup fund to get you through say 6 months of tough times - you need to start to think about investing instead. Saving rates are good at the moment and a very reasonable way to invest, but they are an anomaly compared to the previous 10 year period where saver rates fell below 1.5% per year. Compared to having your money invested in the stock market during that time, you would have lost so much compounding potential and the real world value of your money would have been eroded away if you left it in savings accounts instead. The point being that you need to be dynamic and flexible, adjusting to the financial opportunities that are available to you at the time.
