My only reason, to impress other people.
There are only three things that receives loved unconditionally, one is women, second is children and the last one is dogs. I, as a man, must have everything especially money in order to be loved.
Even I don't really like to sacrifice everything to make money, but as a man, I'm forced to do that.
I've sacrificed my time, my happiness, my energy, my friends, my moral, etc just to earn as much as possible.
You lead a simple life so it reads.
Kids you need to educate, or do you wish to have kids with weight issues, joking a cellphone instead of the garden?
Wife's who are impressed by wealth switch often, there are many people with money, and many more who play rich.
