The Dog/Gemini's wanderings are modulated and conform to a pattern that is predictable to the knowing eye -- the avoidance of the unpleasant. It's really as simple as that. You don't like being couch-bound; a regular exercise regimen is recommended, and indeed preferred by that Gemini athlete in you.
That indescribable quantity that you're searching for can never and will never be found, but don't let that discourage you -- while your Dog half has you out scouring the surface of the earth, so many other worthwhile experiences will pop up and shake hands with you that your endless peregrinations will be well worth the occasional spot of trouble along the route. Beware the lover who refuses to share all -- they're not strong enough to run your course with you, and will abandon you at the first obstacle.
