In my experience the beginning is the hardest time. Everything goes easier and easier day after day. And then you see a few simple fundamentals:

1. TOP SEO rules, TOP SEO mistakes, TOP SEO tools, the best SEO strategies etc. are repeating from website to website.

2. You make a remark for yourself, that there are only few sites where you find interesting and fresh information. You observe them daily.

3. If you want to make deeper investigation of SEO, you have to enter “schools” or online studies offered by large companies, e.g. “Google Advertising Professionals”. There is no doubt, that people who created search engines know the most about the thing.

4. Make your own websites dedicated for different fields of human life. You will learn the most important things from them.

And the key rule:

5. Use your own head no matter, what are you reading, applying or studying. Do not copy paste.
