My life purpose?
In fact it's quite "narrow" for me. I don't go for world peace or inspire the whole nation etc etc You get the idea?
I work towards my goals of providing my parents a comfortable life when they retire. They don't need to worry about money anymore.
I would like my future wife to have a choice of whether she wants to work or not. She can choose not to work for her whole life and I can still provide her financially.
Simple as that. Period.
