I'm glad he mentioned the importance of doing and showing rather than just studying the material. But be careful-- like many careers, computer security favors specialization, and its easy to get more or less pigeonholed into a few areas. This is further complicated by the rate at which technology changes. I spent 6 years in computer security right out of college, and most of it was PKI and assessments. To stay on top of other areas of security required constantly learning and doing stuff on my own, outside of work. Even if you make it a profession, you have to keep learning and doing if you want to be considered an expert or specialist.
