Hyperfocus is really outside of your control, for the most part. You can’t just decide to hyperfocus and have it be so. It’s more about getting so engrossed in something that you’re interested in or passionate about that you’re super focused on it.
The neurology of the ADHD brain is such that motivation is triggered by urgency and interest, not be importance, as in a neurotypical brain.
