At various times during my life I have had much more money than I ever needed and the strange thing is that it never made me feel happy. I think there is nothing worse than having a lot of money and being alone with it as this happened when I was quite young and single and whilst i was able to do almost anything I wanted it made no difference at all.
Growing older and being in a relationship I find that money does make a big difference in being able to make choices be comfortable etc. So I guess what I am saying is that it does bring happiness to a certain degree depending on life circumstances and moreso when it brings happiness to other people. Can't really understand people who say that winning the lotto or having far too much money makes them feel miserable. If that's really the case why just not give it to charity.
