I studied for the Certified Information Systems Security Professional (CISSP) exam for almost two years.
The first year and a half were in fits and starts. I was struggling with the prep material I’d found, and couldn’t get motivated.
What finally helped me buckle down and study in earnest was finally scheduling my exam. I was scared to finally do it, but it was the best motivation I could give myself.
I was afraid of having to reschedule, since there would be a fee. The week of my exam, I had a death in the family and had to reschedule. I was surprised that the fee didn’t make my motivation fizzle, it increased it.
So do it. Schedule your exam, and start getting ready.
