Aversion is painful.
No pain, no gain is trying to express the core of the issue.
A healthy mistake is one that allows suffering without doing the harm to the self.
Pain can led to many bad habits or to many good habits.
Awareness will point out the meaning of the pain.
Exercise like meditation can produce good outcomes: simplicity, compassion and patience.
Managing life requires many forms of exercise: journaling, meditation, visualization, reading, writing, research, walking, talking, thinking, feeling and lots of work, play.
Going with this flow is real happiness.
Preaching non-violence led to inner peace which is another good outcome.
In this sense, pain and suffering can be a kind of aversion, when practicing good habits will produce better outcomes.
