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.
This is really a good lesson that meeting household expenses from the money you have and also saving from it is a tool used only for small tasks, but on the other hand, if we take on big tasks, we need to do separate work for it, which we should have, in which we do not get enough pleasure and we are successful in completing it easily.
