I want to learn to draw two and more light source о.о

It's a scrap w\for my post (but he will be on Russian in another site :D)

But...
I want to say, that even psychology itself is subjective.
I read psychology and psychiatry since 2012-2013 years, and I understood, that it's a subjective science. Everyone is unique.
I understood, that this scienses try to change people, to make their personalities comfortable for society.

But, I can to mistake. I don't to affirm, that I right. I can to change my opinion in future.
