In a recent LinkedIn post, Eric Sim delves into the essential human skills required in the modern workplace, categorizing them into two distinct yet interconnected areas: skills for dealing with others and skills for managing oneself. Sim argues that while external-facing skills are vital for professional advancement, the ability to navigate one’s internal landscape is equally, if not more, challenging and critical.

Sim begins by outlining the outward-facing skills necessary for professional interaction and influence. He notes the common workplace objective of motivating others to achieve desired outcomes, whether it’s securing clients, fostering collaboration with colleagues, or negotiating promotions and raises with superiors. The skills involved in these interactions, according to Sim, include negotiation, presentation, storytelling, writing, relationship building, and empathy.

The Challenge of Self-Management

However, Sim posits that managing oneself presents a unique and often underestimated hurdle. He points out that complete control over one’s own actions and impulses is elusive, making self-discipline a significant challenge. Sim highlights common struggles, such as the difficulty in maintaining healthy habits like exercise and proper nutrition despite knowing their benefits for productivity. He observes that after a demanding workday, the allure of passive activities like social media or entertainment often outweighs the effort required for self-improvement.

“Dealing with ourselves is not any easier because we don’t have 100% control of ourselves.”

Furthermore, Sim touches upon the creative and adaptive aspects of self-management. He questions the ease of generating innovative ideas when individuals are unaware of their own mental constraints, asking, “how do we think out of the box when we don’t even know we are in the box?” Similarly, he addresses the resistance to change and the discomfort associated with stepping outside one’s comfort zone, noting that it’s often easier to remain a passive observer than to be an active participant.

Essential Internal Skills

The human skills essential for navigating this internal terrain, as identified by Sim, are discipline, creativity, adaptability, and resilience. These are the traits that enable individuals to persist and push forward even when faced with adversity.

“The human skills required in dealing with ourselves are discipline, creativity, adaptability, and the resilience to take one more step when everything is going against us.”

Corporate Focus on Human Skills

Sim also draws attention to a broader corporate trend, referencing a Wall Street Journal article that highlights significant investments by major firms like Ernst & Young, KPMG, and PwC in developing human skills among their employees. These companies are reportedly investing in areas such as adaptability, innovation, judgment, critical thinking, empathy, and creativity, alongside AI skills. Sim suggests that this renewed emphasis on human capabilities may stem from a realization that investments solely in AI are not yielding the expected returns, prompting a strategic pivot towards cultivating uniquely human attributes to maintain a competitive edge.

“It seems like investing in AI is not giving companies the expected return. So some of them are focusing on human skills to stay competitive.”

In conclusion, Eric Sim’s analysis underscores the dual nature of essential human skills in the professional sphere. He emphasizes that while influencing others is crucial, the often-overlooked discipline of self-management, supported by skills like resilience and adaptability, is fundamental for sustained success and competitiveness in a rapidly evolving business landscape.
