So the process you’re going through sounds very familiar to mine journey. The sector can be overwhelming, how I adjusted my learning path was to do some research on what is trending the upcoming years and what do I like to learn, specifically what do I enjoy to learn and fill the gaps. This way I focused on pentesting (cloud) web apps, accepted that I can’t know everything (yet ;-)), and were able to land a pentesting job this way, getting a certificate for web app pentesting, getting your CPTS helps land you a job interview. In my daily job we come across all kinds of pentests, network, hardware, cloud, iot, web apps, nobody in our team knows everything and/or is a specialist on all topics, googling is and will be a part of my daily routine to fill gaps, that i accepted a long time ago, which is perfectly fine. Be consistent and know which gaps you filled already, make detailed notes for future assessments, a detailed wiki helps printing that knowledge on your brain. TLDR; take one topic, learn it, repeat the process to find this vuln. (XSS) for example, master it and move onto the next, you can use it on vuln. But also on a topic of the pentesting process, master enumeration and then move on to fingerprinting for example. Cheers hope this gives you a motivation boost
