In this generation money is very important, in everything you do money is always involve such as buying all your stuff like food, house, clothes all types of bills and anything that involved money. You cant also say that money cant buy happiness because if you have money everything could be easy for you cause you can afford everything you want that can make you happy
I think that quote only meant you can't "directly" buy happiness. It's quite because how rich people wanna act ungrateful of the things that they have so they would seem troubled. They always think, "I'm rich but I have no one." when they could have been donating money to the less fortunate ones and become happy. People put their happiness on material things such as iPhones, or whatever the popular culture dictates you to buy and then wonder how they are unhappy despite of having so much. After hours of research, I learned that you don't really need a romantic relationship with someone in order to be happy. You can be happy by simply helping other people and seeing them become a better person or survive for the day, all because of your help. Without this, you can never be truly happy.
Right now you're thinking that you're going to be genuinely happy once you got all those money and be able to buy the things that you want. You're excited because you haven't experienced it yet. But at some point those things would become rather normal to you. You will get used to that certain lifestyle and you'd notice that nothing has really changed about you except your possessions. There are other ways that you can be happy because of money and it doesn't always have to be because of material things.
I agree to what you said especially about how we can feel happiness just by helping other people. I also had the same realization about the importance of money in my life. And I'd say money is a way for us to buy experiences in our lives that will bring us happiness. We cannot deny that without money, we won't be able to do the things that would really makes us happy. It's just a matter of how do we spend, to whom should we spend it, and what should we spend on with our money that would really make a huge impact in our lives and hopefully, with other people lives. I hope I made sense in the value of money in our lives.
