I read docs, I read code, I read SO questions, I read forum posts, I read blog posts, I read chat histories, I read GitHub issues.
And then, after I lost 1h-20h I ask someone.
Why?
When I started programming, people didn't help me. They were angry when I didn't know things. They laughed at me when I didn't know things. They explained things very badly. They didn't have time to explain things. They didn't know what they were doing themselves.
