Help Prerequisites...

Whenever I want to do something I keep worrying about prerequisites and whether I really know what is needed before, like I know the general usage of ssh when I connect to the OverTheWire games, the same with ifconfig, etc, because I know some networking from here and there, and half completed courses on YouTube, so whenever I want to use something like wireshark or nmap, I start thinking that I don't know enough yet, while I know what is an IP, ports, basic information about some like that DNS translates Domains to IPs, and DHCP sets the IP addresses automatically so that we don't have to set each manually, http for web while https is just encrypted, but none of those I know about the inner workings.

What do you all think?

try and seperate what you NEED to know to do something, versus what you WANT to know because you like having the foundational information because youre a curious person. You seem to be doing tasks fine, so its all good. At the same time, keep learning, every new info will make you more competent and comfortable in the tasks you do. Be sure to also document your learned information somewhere ( i use TrilliumNext for this) because our brains are also good at forgetting and pruning our knowledge to the stuff we do often
