Everything in moderation: Even suffering.
Why do we suffer? Very complex question: but from a base-level biological perspective, it’s our body and minds telling us something is wrong.
The proper way to respond to suffering is not to crawl into a ball, but to get off your ass and do something about it. It’s a driver of life.
And from an evolutionary standpoint, those who didn’t suffer died out.
