Should I become filthy rich rather than finding my soulmate?
Maybe. Why do you want to choose?
I think money would make me happier than love.
That wouldn't actually make you happier.  Studies show money stops making you happier after about 70k a year or so.
I think you are wrong. If I want money I shouldn't shy away from hard work.
Hard work will get you money but the money won't make you happy. Being with people will make you happier and having good experiences will also make you happy.
