It takes work to stay in the middle on an issue.

It is not a fixed state but a moving target. It’s a balancing act that fatigues.

Your mental/philosophical core must be stable.

To stay in the middle takes constant effort. The simplicity of the extremes pulls you constantly, begging for you to lean, then fall, in either direction.

Those who are not in the middle will actively try to pull you in their direction.

Forces encouraging you to stay in the middle are quieter. 

Weaker

But worthwhile.
