I'm a bit frustrated. I'm 23 and I finished a Bachelor's Degree in Computer Engineering last 2015. Working on a career path in cyber security. Is it normal to just understand and test the concepts and not fully memorize everything? It really bothers me that I feel I don't know anything despite developing small tools, testing other people's work, reading about related topics and playing with Kali.

what do you want to learn ? out of Google

@rajilsaj I'm actually learning step by step at the moment. Gonna concentrate in the wireless topics under cyber security before I proceed to other topics. I was actually a mess because I keep jumping from one topic to another without finishing them.

@nateye I understand your feelings. I myself find myself on the same page with machine learning. I'd say make projects of your own and one at a time. You may have done things in university, but nothing beats self-learning.

And as for finishing the projects, do one at a time, over the course of 3 days, for example. Without setting times / deadlines for full-time focus on single project, I think it's easier to drift and scratch the surface of yet another tool / topic.

@honeyBadgerJeff Thanks for the suggestion. I'd be sure to work on some. :)

Everyone sucks fresh out of university. Employers know this, they sucked too at that point also.

They know that you will continue to suck for a year or so but will eventually become industry proven and an asset.
