find a richwoman/man is very easy, the problem is are you can make him to love you? it's not easy to make someone falling in love. 
better we hardwork and feelling your dream in your mind, then you get more spirit to be richman.
That would be a desperate move for us if we think that the only way to get rich is to find a luck with other person I think. And yes you are right, it is easy to find someone rich especially if you are a beautiful woman, you might find an old man but very rich. The thing is how long will you embrace the burden of not really loving him and just for the money. But as always they said that you could always develop the feelings if you are always with that person even if he is that old and if he treats you nicely. Otherwise, if you do not want that, we could always be determined to reach that goals and let true love find us.
