lol, yes I guess that’s true. Sorry it’s a bad habit. I edited the post completely after thinking about what would be the best advice to give… it’s still long though 
But I’m actually summarizing. The work still falls on you. Learning these thing takes effort, but after that effort you know it, it feels great that you know the answers and that you fixed a gap in your understanding. There are a lot of gaps.
There is a lot of science in art, everyday I’m humbled by the depth and knowledge needed in art, basically to draw something you have to understand it inside out. It is not an act relaxation, it an act of extreme focus.
I believe there are huge gaps in generic art education vs what is needed. I’m studying light now. Most tutorials show you that sphere diagram, or explain those directional arrows to predict the shadow shape and think that’s all you need. I’m learning that’s not even 1% of what needs to be understood about light.
So I’m afraid we all have a lot of reading, learning and drawing to do.
