In short, the money we didn't work hard for is easy to spend, but the money you know you worked hard for is sure to be valued truly and rightly. There is the feeling that you will value every single cent of it.
I don't believe that money made without much effort is easy to spend it is dependent on the individual that has the money to decide whether to make judicious use of it or to spend it on frivolous things. You can't tell me that because you made money so easily is enough reason for you not make good use of your money it is a very wrong narrative
I think both of you are right. If we take lottery winners as a sample, we can hear stories that they became poor again after some time but then there are also who became more richer because they use the money properly. They invest it in the profitable assets, use to create their own business, and so on... No matter what way we obtain the money (hard or easy) it is important to spend it wisely so that we won't become problematic later on.
We should advance think the consequences if we are feeling greedy so that we can prevent our selves from doing the wrong thing. Thanks for the nice tips by the way @OP. May all of us can apply it and improve our mindset when it comes to money
