I think people spend way more time than they should denegrating Certifications.
Regardless of whatever qualifications you have, degree, ms certs, including mcm's / mca's (no disrespect to them), once you stop in that journey of life long learning your abilities will, over time, degrade.
A Certification or any other type of education for that matter, should never really be seen as an end in itself.
My point? Don't be put off Certifications, you just need to put what they mean into some kind of context.
They are nothing more than another step you've taken towards learning and mastering your craft.
Ultimately, the experience you gain over time will be more valuable than any certification or further education you might undertake.
Go with what you love and have a passion for, the rest normally follows.
