Title: I&#x27;ve been programming all my life and creating drawings&#x2F;diagrams of anything comes very natural to me. While this happens all the time in my head, I still grab a pen and paper sometimes when the mental overhead becomes too much. 
Currently, I&#x27;m struggling with a junior colleague. He comes from a different background (sales). Adjusting existing code, fixing and improving features is not a problem for him, but as soon as something becomes more complex he struggles a lot - even simply drawing it on a paper completely blocks him.
I&#x27;m looking for advice or resources that can help him improve this skill.
