It is realy good to save money, whether you do it on a bank or do it ourselves. I dont really get what you are saying, but I think you are saying good things about saving and investing. The more we invest the more the profit, the more you save, the more you can get from the future and the more your savings amd investment, the more money you can get in the future, I think that is what you are saying. But in these two I prefer to save than to invest, saving is a way of investment too, though in saving you take care of the money while in investing, you gave it to someone else.
The journey will always begin with saving as you cannot invest directly without building a initial capital so our primary concern should be to save money and after saving enough funds you can start looking for best possible investments and that will help in growing your funds in long run.
