I actually and genuinely agree with you mate,spend less but save some for later because when you loss your money you gonna loss Alot of people whom you think where just after the real you,not knowing they are just with you because you have what is to being giving which is money ,money is the roots of all evils,but really friends got your back with money none without they only believe in what you do.
Saving some amount for the future is a good idea and everyone should know the value of saving because if you have no money for emergency purposes then no one will help you in such dangerous circumstances.
Money is important but if someone is with you just for money then there is no need to have a friend like this. You should have the ability to differentiate between good and bad friends and if your friends are with you for their own purpose then I think he is not a true friend.
