Infinite Loop

Just when u think u are goin straight, comes the cynic, tells u ur wrong, and goes away. The turns made as such, now shaped into not so a defined one. Logic seems the easy way out. But if purely logic were to lead you away, what defines if you are lead astray ? If the focal point is where we are headed, how do we find ourselves in the same state as the start with miniscule deviation - so was all this treading along a single loop ?
