I would put it a little differently. I don't like the word "save". For me, this word is associated with poverty. But the expression "spend wisely" is more suitable. If a person has a goal or an idea for which they are going to save money, then there is motivation. But to deprive yourself of a lot to invest in the future, to be honest, I don’t see the point. No one knows how long your life will last, and depriving yourself of everything, constantly saving, at some point may seem very stupid.
The whole idea of saving will not also be possible as you have also your own bills to pay and basic needs to attend, so certainly its more on spending wisely through money management. And when you invest, it doesn't mean that you have to invest all what you have got, instead invest only a portion of you hard earned money so that if you lose, you won't be badly affected.
When we do have money came from our dayjob or other source then of course it would really be needing that kind of money management so that you would able to save up money but it would really be
still needing to be deducted from expenses,needs and wants which is a normal thing and the rest of those amounts would be save for emergencies and possible investment that you would really be tending
to get engaged on but there are lots of considerations before you would make such step.
Investing should never considered to go all in to it because you should allocate on the amount which you can only afford to lose and not spending it all
specially to those emergency funds which had been allocated.Proper money management would be the key.
