8. The more visible you are, the more money you make

Yup, it's really that simple. No matter what professional services you offer, you will ALWAYS make more money by being more visible.

A blog is the most inexpensive (it's actually FREE!) way to promote yourself to potentially millions of people.

If that is so, why aren't more people blogging? Why are there only 30 million bloggers? (And most of them are not even serious bloggers).

Simple: People can't change their mindset. They still rely on their employer (who wouldn't hesitate to ditch them at the first sign of financial trouble).

Bottom line: you're on your own, Jose. Take control of your career. And realize that a blog may very well turn out to be your best career weapon.
