Money can buy those material things and can make you happy for the mean time but we cannot buy our own happiness, we do have our own feelings that we cannot trade for money.
Consider spending money for the good of those you love the most. If they are happy because of that money, does it make you happy too? If it doesn't make you feel happy then something is wrong with you.
You can use your money to attract new friends, not by bribing them but by sharing things to them. Though, some are hypocrite, as if they are not using money everyday and when they use it, it makes them happy too.
