Before Others Can Do it to you, do it to yourself.

McMillon embraced change, even at the expense of short-term losses. Under his leadership, Walmart has become one of the few traditional retailers capable of competing with digital-first companies.
Lesson: Current business Legacy businesses need to create the disruption. Reinvention is not a response, but it is a duty.
Put Values before Value
McMillon is very concerned with stakeholder capitalism. Although Walmart has been known for offering low prices, it has expanded its mission to be socially responsible, environmentally friendly, and to bring dignity to its workforce.

Employ the Technology to Serve, not Replace
Under McMillon, Walmart adopts a human-centric approach to technology.

Walmart’s tech investments focus on convenience, speed, and effectiveness, maintaining its personal touch.
Lesson: Technology should be a means of uplifting people and not obliterating them. Machines supplement the workforce of the future, not replace it.
Accountability and Transparency build Long-term Credibility
McMillon is unafraid of tough talks, proactively addressing issues such as gun violence, climate change, and labour protests. He led Walmart to halt sales of certain guns and bullets after mass shootings and engaged in national discussions on gun safety. He promotes diversity and inclusion through internal task forces, hiring targets, and diverse leadership to reflect Walmart’s global customer base.
Lesson: Being a leader in today’s world means taking a stand. Inaction is not a thing of neutrality; it is a thing of missed opportunity.
Never be above Keeping Humble
Despite being the head of one of the world’s largest corporations, McMillon is said to be a humble and down-to-earth individual. He makes himself clear, takes bold decisions and gives credit to the team. The influence of his humility over the years of climbing the ranks speaks to Walmart’s broader workforce.
