I usually think back to how I got to a certain subject, basically retracing my own steps.
something that people really dont understand about ADHD is that we dont “jump from one idea to the next”
we have very fast, very associative minds that connect ideas. we have a train of thought, it just goes WAY faster than yours!
example: im thinking about dogs. that makes me think of pitbulls, which makes me think of an animal planet show i enjoy. the show connects to tv in general, which makes me think of my favorite cartoon. i associate my favorite cartoon with art and animation, and i wind up thinking about shading techniques.
TL;DR: having ADHD is kinda like playing a lifelong game of 7 Degrees of Kevin Bacon
