Speaking of flow, do you pay attention to how your brain feels when you spend time with other people? Is there a brain that enhances or triggers a sense of flow when you are together? These are the brains you likely want to spend the most time with, around whom your brain is relaxed yet alert, comfortable and yet energized, genuinely happy and creative. Likely there will be only a few of these brains during your lifetime . . . some have said the biggest mistake they ever made in life was failing to nurture relationships where they had a strong brain connection and, instead, went for what was familiar or was touted as being indicative of a good relationship: sexual tension, for example. For many, what is familiar is neither healthy nor desirable, and may not promote “flow” in any way, shape, or form.
