Like anything, you cannot predict the future. You might find your perfect dream job as a result of having the certificate. You might just as easily miss out on the opportunity to take your perfect dream job because you're busy acquiring the certificate. Anything can happen.

My personal advice is to ignore any future advantages that may or may not come as a result and focus on doing it because you simply want to do it. If you enjoyed the process and feel fulfilled at the end, it doesn't matter what may come as a result. If you need to work hard to sell yourself on the idea of doing it, it is probably not worth doing.
