Thanks! I appreciate your feedback. It's sometimes easy to forget that you learn by doing. I guess it's easier to see the context if you know how to do it and/or have some hands-on experience. Actually, I think your answer makes me realize I need to put more focus into hands-on training for the stuff i'm not 100% on. Maybe more so than reading about it. And of course, a certification does not hold much value if you are unable to perform the tasks required in real life.
