I read as much as time permits. Currently I am working towards building micro SaaS side projects to supplement, and one day replace, my salary. I use them as a way to learn new tech as well as experiment new tools/libraries.
I try to understand things as clearly as I can. When I was writing articles for my crypto blog, I read as much as possible about SEO. I managed to get the articles to rank in the top 3 of google search results.
