The forward-looking brain

The purpose of the brain is not to perceive correctly, but to act correctly.

Perception is not a tool to see, but a tool to act.

Biases are not bugs of the brain, but features.

Neurons do not evaluate the past, but infer the future.

Pain is not a sensation of the past, but a guide for the future [to avoid further damage].

Happiness is not a place to reach, but a direction to follow.

Emotions are not a judgement of the past, but one of the future.

(Humans do not mourn the past they lost, but the future they lost.)

Making emotional decisions is not a deviation from the original design of the brain, but making rational ones is [because emotion is the metric the brain ultimately uses to measure success].
