What advice do you have for people looking to enter the field? Start figuring things on your own. Don’t rely so much on courses and degrees. Explore, test, try, and practice. Install your own “pentest lab” and attack it. Play with exploits and see what breaks when you run them. See what happens when you combine technologies that weren’t necessarily made to run together (something seen on large corporation networks and systems). In short, be a self-taught person. Read books and get in touch with like-minded individuals, learn, and pass the knowledge. I’d rather work with someone who is self-sufficient and has no degrees than someone with a PhD and no real-world or practical experience.
