Of course saving is not enough at all, that is one thing most people normally forget. However, saving can only be a enough when you have a good investment plan for yourself, without that there is no how your savings would be able to cover all your needs. Normally having a savings is quite good but let it be that you have an investment that would be fetching you money all the time because saving alone might not be that fast in times of achieving goals.
I think what must be considered in this case is the urgency of the intention to save itself because in the end if you look at the purpose of saving is for the short and medium term so obviously there must be other options if you really want the goal is for the long term so we choose to do some other actions such as investment which is indeed a more possible goal for the long term, especially in terms of results.
Saving is good, clearly anyone will not be able to argue with this but indeed when talking about whether or not it is enough for quality changes, especially for our finances, it will not be enough because after all the function for savings will not be able to last for the long term, especially for now where the value is shrinking more and more, saving and using it for the long term is clearly not a good choice.
