The stand has always been that you're either saving up today for a better tomorrow or you're eating it all up today without putting much consideration into what the future holds. Either way, what you choose to do or not to do today will certainly affect you in the future.
Keeping out a certain percentage of your income for future use is a necessity most expecially in an economy that's as unstable as what we've been witnessing these while. Regardless the urge you feel to spend even when you're earning real good, the ability to keep some for the future either in the form of savings or investment helps make the future much easier for you. You could spend it all at the present and still do well in the future but that's a very risky thing to do as someone that's financially wise. Every future oriented individual knows better that it's better to sacrifice the present joy for the future gains.
There is no reason not to do that because if we want a better life in the future then we have to think about it from the start.
Every desire that we want to achieve certainly requires sacrifice and what we do today for a better future is a form of sacrifice.
In fact, I don't think there is any sacrifice or dissatisfaction because we set aside from our income for the future because there is a goal that we want to achieve that makes us more motivated for it.
In this world I think the majority of people think so even though there are some who don't do it for certain reasons but personally I always think that for the future is something that must be fought for and it must be done no matter what.
