Don't look at money as the deciding factor. You gotta choose what you like, don't choose one job over another just because it makes you more money. It won't bring you happiness.
To be able to spend money on what I want to buy. For example, as I am a soccer addict, I wish to be able to buy top quality soccer boots whenever I want to.
Because is way better then making less money...com'on! everyone haves dreams and things they want, you need money for those, lots of them...
