The ADHD brain excels in 'divergent thinking' due to a less active Default Mode Network (DMN) filter. While a neurotypical brain filters out 'crazy' ideas early, the ADHD brain makes rapid, bizarre, and highly innovative connections. Generating these ideas releases massive spikes of dopamine in the Ventral Tegmental Area (VTA).
However, building a business requires 'Convergent Thinking' and 'Executive Maintenance'—focusing rigidly on a single path and executing chronological steps. This requires the sustained activation of the prefrontal cortex and a specialized form of dopamine transmission that is notoriously deficient in ADHD.
When the brain hits the 'implementation phase' (e.g., waiting 10 days for IRS paperwork to clear), the novelty vanishes. The brain's dopamine receptors begin starving. The brain identifies the new, most obvious source of dopamine: a brand new business idea. The pivot from the old business to the new business is a chemically-driven survival reflex to avoid the agonizing under-stimulation of administrative work.
