We humans can be quite indecisive and unstable when our emotions are involved. The human mind is continually racing and ravaged with different thoughts, and these can leave one confused on how to act, when to act, and how to make decisions. Hence the importance of understanding how our emotions work, where they come from, and how to express them.
To put it plainly, our emotional resilience is what stands in the gap and keeps us from losing it, especially when it seems like everything is falling apart.
