I used to feel this way and when I had time set aside to learn I would just sit there and waste almost all of my time figuring out what to study because there was so much. I would waste all my time doing this and not really learning very much because the breadth of stuff to learn was overwhelming. Eventually I just forced myself to choose one thing and focus on it. When I get to the point where I feel competent in it, whether that's a day or 3 months, then I allow myself to move onto something else. Don't get stuck in your head. Just choose something and commit, no one knows everything, the posts are by hundreds of people, each with skills in different areas. Know one knows it all.
