controlling spending too but...
I'd say that for most people it would be so much easier to make $5,000 more each year than it would be to cut $5,000 of expenses.
You can only cut expenses so much, but you can raise your income by multiples of your current income. This is America. Making money in our country is easy. Really, really, really, really easy. Get the right degrees/certifications. Work hard. Be focused at work. Be consistent at work. Stop wasting time on things that don't matter.
