Saving should not be underrated since it is through saving that we can gain funds to invest without borrowing the capital. Of course, we shouldn't stop with saving alone but use it as an edge to invest.
I think it isn't, because a lot of people are doing it already, as there are great perks that entails with it. By saving, it allows us to multiply the small amounts that we save and it was mainly used for emergency situations and not really to invest on something. If we want to invest on something, it is still possible by using the amounts that are left in our salary. I think it's not wrong to lay-low or subside with savings, if you are really lacking in budget, and I think it's more easier to do and can be less risky for a while than investing.
When the time our investment turns into a success, that will give us bigger opportunity to save more funds so we can prepare for a bright future ahead, otherwise saving alone won't get you that far from the time you've started.
Savings, doesn't need to be big but it is usually done using the residual money that are left from our salary or something.
