It is not a trait that can be taught or learned in a traditional sense, as it goes against the values of compassion and empathy that are typically instilled in individuals. While one can develop a tougher exterior or become more focused on their goals, true ruthlessness is not a desirable or ethical trait to cultivate. **

Ruthlessness may lead to short-term gains by allowing individuals or organizations to prioritize their own interests over others and make aggressive decisions. However, in the long run, ruthlessness can damage relationships, reputation, and trust, which can ultimately decrease returns. Building strong, collaborative relationships and maintaining a positive reputation are often more sustainable strategies for long-term success and higher returns. Therefore, while ruthlessness may provide initial gains, it is not a reliable or sustainable approach for increasing returns in the long term. **
