1. Get Paid What You're Worth and Spend Less Than You Earn
It sounds simplistic, but many people struggle with this first basic rule. Make sure you know what your job is worth in the marketplace, by conducting an evaluation of your skills, productivity, job tasks, contribution to the company, and the going rate, both inside and outside the company, for what you do. Being underpaid even a thousand dollars a year can have a significant cumulative effect over the course of your working life.
No matter how much or how little you're paid, you'll never get ahead if you spend more than you earn.
Often it's easier to spend less than it is to earn more, and a little cost-cutting effort in a number of areas can result in big savings. It doesn't always have to involve making big sacrifices.
