It's a lowkey skill that everyone has to learn. If there's one person telling you about this, you shouldn't take that person's tip personally because he don't even understand what he's saying. I think another trap that many are saying is that "don't save your money but invest". Why I am telling this? While there's truth that you have to invest your money but not everyone can practice risk taking that quickly. So the technique of saving is teaching you not really how to save money but the principle of handling your money very well. And I believe that whenever you're able to learn how to be a good money saver, that will help you to become a good investor as it will be developed too.
