Both, but with a little extra emphasis on saving money. I like to preserve resources, make my lifestyle more efficient, and find ways of producing things myself rather than pulling from the "pool" in stores and online retailers. Saving money is also something that can be done instantly, whereas increasing income usually takes a bit of time. As I do manage to increase my income, I try to find productive (i.e. income-earning or educational) ways to spend that increase as opposed to using it for normal everyday things so it'll hopefully lead to an additional increase.
