Optimal Challenges
This idea of an optimal challenge is an important recurring theme. We must strive to challenge ourselves optimally. If we do not challenge ourselves enough, we can become angry because we are not living up to our potential. If we overburden ourselves, we will become mad due to being overwhelmed and not having the ability to handle everything that comes our way. Therefore, pursuing an end goal in a manner that challenges us, but does not overwhelm us is a path to our highest purpose along with being the way with the least amount of anger.
