Continue to learn and to gain real-world experience. CISSP is not an entry-level certification. Those who have it have sweat it out for many years in the trenches; and those who would aspire to it (myself included) really need to realize that it is a big step forward.
Ethics, attitude, professionalism are very important, because those who have the credential are rightly concerned that those who follow will value and enrich the common body of knowledge.
Start with Associate of (ISC)2. Get real-world experience. Go for CISSP in five years.
