Some simple processes to follow when doing things.
Find what I want/need to learn. Ideally in context of a problem I want to solve.
Read about it on wiki. Find the topic on Learn Anything and learn from best resources for deeper knowledge.
Ask myself why it is the way it is. Ask myself what am I missing and what I don't understand (tackle each dependency one by one).
Write down main ideas I want to cover as bullet points.
Write the article touching on all the main points.
Refactor. Remove useless words and irrelevant pieces.
Know what I want to write about. Write an outline.
Write the book. Refactor continuously.
Read the book. Highlight important parts and/or translate them to wiki as notes.
When finished reading, transfer highlights to wiki. Make review of book on Goodreads.
Follow making workflows outline.
