And, PLEASE... remember that the MVP award is a "Service Award". Although a great many (for example) SQL Server MVPs (such as the author of this article, Kathi Kellenberger and others like Grant Fritchey, Steve Jones, Brent Ozar, Paul Randal, Kimberly Trip, Kalen Delaney, just to mention a few) are very knowledgeable, the MVP award is NOT a "Certification" of knowledge in any way, shape, or form. It's a recognition for "Public Service".
Also please remember that you don't need to be shooting for an MVP award to help others... or yourself.
There's a side benefit to helping others that I wasn't aware of even for years after I started posting answers on forums, writing articles, presenting at SQL Saturdays, etc. It's not only a form of "Passing it forward" that people don't forget, it's a form of "practice" and this great community helps those that help others. No where in the world can you find such a broad spectrum of problems to solve. I especially like the SQLServerCentral.com forums because, if you get something wrong in your post or someone knows a better way, someone else will speak up with their experiences and code and that type of discussion (unlike on some other forums) is actually encouraged (even if you're not nice but it's better if you're nice). Taking some common problems and learning the "gazintas" and possible solutions about them well enough to write an article doesn't only help others... it helps you because there will be comments thanking you and some comments about the code (some with a better way and some that you'll have the opportunity to prove are not) , and some comments on how some people didn't understand. That latter one is huge (especially if you follow up with those people to explain better or differently) because it tells you you have a possible flaw in how you communicated in the article and helping the folks in the discussion to understand the point you were trying to get across will not only make you better at writing articles, it'll make you a better communicator both at work and in life in general.
The same goes with taking it to the next level and speaking at Lunch'n'Learns at work, user groups, SQL Saturdays, and maybe even some of the larger events like PASS SUMMIT, SQLBits, whatever! People will tell you whether you did good or bad in different areas and they will sometimes offer up suggestions that are immensely helpful.
It's totally amazing... the more you give, the more it seems you get back, especially if you're open to suggestions and maybe even a little criticism.
Don't shoot for the MVP awards. Instead, shoot for being an MVP every day. The MVP award may or may not appear but you'll have made an incredible difference to a lot of people and, in particular, yourself in ways you can't even imagine now.
