I have heard of those certifications. Thank you for your advice. I will definitely check out these applications. I guess I was just being lazy when I wrote that I don't have time. Of course, I have time. I took some time to ask this question, so I obviously care enough to put in time to learn. My problem, I believe, was I didn't know if I putting in time to resources that I had myself discovered was worth it. This is coming from my experience on reading certain protocols' wikipedia entry, watching tutorials etc. and not gaining useful knowledge and understanding after spending dozens of hours into it. So I was being cautious of that. So, what was missing, until now, was some guidance. With comments such as yours and many others here I have enough confidence that putting in time into these resources would not only be worth it but also would be an efficient use of my time. So thanks for that as well.
