To certify is a huge step - it changes your identity (those capital letters at the end of your name), it proves to others that you're qualified, and more than anything, it increases your probability of getting hired and getting paid more.
Passing your exams not only tests your knowledge, but also your perseverance and dedication. To succeed, you need to devote a good amount of resources, time and money to earning your cert. And the tricky part can be deciding what those resources are, how much time to invest, and how much money you will realistically spend.
