You only grow when you challenge yourself according to ideals. Then challenge = growth.

From OptimalScience

Summary

Growth, or an increase of virtue, occurs when an individual desires the growth and willingly embraces a challenge. The psychological disposition of embracing a challenge has been described as having intrinsic motivation, as opposed to extrinsic motivation (2). Intrinsic motivation is conducive to learning, competence, and growth, while extrinsic is not, and can actually hinder the process (2,5).

Intrinsic motivation occurs when a person experiences joy and fulfillment in approaching the task or challenge, and their actions have an "internally perceived locus of causality" (2).


central reason why this occurs: frustration when outcomes are not achieved.
