I think the better way to look at it is how passionated are you about your work. How hard will you work for money in my opinion does not create good energy. But working hard about your passionate will create great resources. Have the right motivation and you will get there.
I would love to work in the music industry as an recording artists, and also become a model if possible. I am willing to work as hard as my body will allow me to work, I do not sleep because time is money and money motivates me.
