Hey! I totally get where you're coming from with wanting to tackle CISSP and CISM on your own. When I was studying for my certs, I found the CISSP Official (ISC)² Practice Tests book really helpful for getting a feel for the exam questions. I also used Cybrary for some online courses, which made certain topics way easier to grasp. For CISM, definitely grab the ISACA CISM Review Manual; it was a lifesaver for my prep. Plus, connecting with study groups or online forums can really help keep you motivated and share tips.
