# Local Minimum

Rational thinking is marginal. It only concerns about the locality.
So it converges to the local minimum.

After you reach the local minimum, what you see are worse than what
you already know. So it converges to what you already have known.
Maybe this is what getting old means.

But there is no guarantee that things are convex. Convexity means
there is only one minimum. So that the local minimum and the global
minimum are the same. Not everything is like that.

Until you find the global minimum, you need to endure mediocrity.
You need passion rather than rationality for that.
