ADHD brains tend to lack dopamine in the frontal lobe (afaik). People with ADHD therefore seek out activities to boost dopamine. Some can be destructive and harmful (drug, thrill seeking, destructive relationships) or some people find hits from problem solving - mathematical problems perhaps, relationship problems, or coding problems. You are creating / building / solving. It probably gives you a hit - and your subconscious is sensible enough to realise some of the other options are really bad for you, so rewards the less destructive way of getting a hit.
