Simple maths.

It appears to be a discrete function. In fact, only two options are possible: 0 or -100.

There's nothing between 0 and -100. -20? -50? No, these numbers do not exist.

There are sometimes illusions of positive numbers. But, that's all that they are - illusions.

And even if not illusions, even if real, it's better to keep to 0 anyway. Then -100 won't seem that negative after all. -100 only seems such a low number when comparing to numbers such as +100.

Keep to 0. Keep to neutral.

Be nothing. Feel nothing.

Simple maths. Works all the time.
