Dame Maggie Smith, one of the most celebrated actresses of her generation, left behind a legacy that transcends film and theatre. With a career spanning over seven decades, she masterfully embodied a range of roles, from Shakespearean tragedy to the whimsical Professor McGonagall in Harry Potter. More than her on-screen presence, Maggie’s journey is rich with lessons that can inspire leaders in how to own their space, remain authentic, and rise above challenges. Here are ten invaluable lessons leaders can learn from the life and career of Dame Maggie Smith.

1. Pursue Excellence in Every Role

Whether in a leading or supporting role, Dame Maggie Smith poured the same level of dedication and meticulous attention into every performance. Her ability to shine, even in smaller parts, showcases that true leadership involves giving your best, no matter the task. Leaders, like Maggie, should bring their all to every project, regardless of its perceived importance. It’s in the pursuit of excellence in all roles that true greatness is achieved.

2. Adaptability is Key

Maggie was known for her versatility, seamlessly transitioning between comedy and tragedy, from regal roles in Shakespeare to endearing performances in modern classics like Downton Abbey and Harry Potter. Leaders must embrace adaptability to navigate changing environments and diverse challenges, switching between leadership styles as effortlessly as Maggie switched between characters.

3. Commitment to Lifelong Learning

Despite being a tour de force on stage and screen, Maggie Smith remained grounded and committed to improving her craft. She first appeared on stage at 18 in Twelfth Night, honing her skills as she worked alongside Britain’s finest actors at the Royal National Theatre and the Old Vic. Leaders, too, should never stop learning and refining their skills, always open to new experiences and insights, no matter how accomplished they are.

4. Owning Your Space

From her standout performance in The Prime of Miss Jean Brodie to her scene-stealing roles in Gosford Park and Harry Potter, Maggie Smith had an undeniable ability to command the space she was in. She owned every role, whether large or small, with a quiet confidence. Leaders can learn from this by cultivating a strong presence, one that is built on authenticity and confidence, allowing them to own any space they enter.

5. Rise Above Criticism

Maggie’s path to stardom was not without obstacles. Her own grandmother once remarked that she couldn’t possibly become an actress “with a face like that.” Yet, this criticism did nothing to deter her. Maggie’s rise from humble beginnings in Ilford, Essex, to becoming a beloved global star is a testament to the power of resilience. Leaders must similarly rise above detractors and remain focused on their vision, allowing criticism to fuel their determination rather than stifle it.

6. Be Humble Yet Assertive

Although Dame Maggie won two Academy Awards and numerous other accolades, she often downplayed her talents. Her humility never prevented her from standing her ground, however. She once described her Harry Potter and Downton Abbey roles as less satisfying, showing that even in her later years, she was committed to seeking challenging and fulfilling work. Leaders should embrace humility, but also know when to assert their needs and expectations, especially when their values or standards are at stake.

7. Embrace Teamwork

Despite her legendary status, Maggie Smith was never above working in ensemble casts, contributing to the success of projects like Downton Abbey and Gosford Park. She demonstrated that the mark of a true leader is recognizing the value of teamwork and supporting others in their roles. Leaders should foster collaboration and empower their teams, understanding that collective success often eclipses individual accolades.

8. Lead with Authenticity

Maggie Smith never strayed from her unique style of acting. Whether playing a stern headmistress or a sharp-tongued countess, her performances were always true to herself. Leaders can draw from her example by remaining authentic in their leadership. Authenticity builds trust, inspires loyalty, and creates an environment where others feel comfortable being themselves.

9. Challenge the Status Quo

Maggie was a trailblazer who didn’t shy away from difficult or unconventional roles. From her Oscar-winning portrayal of the complex Miss Jean Brodie to her performance as the eccentric bag lady in The Lady in the Van, she was unafraid of stepping outside of her comfort zone. Leaders should similarly be willing to challenge the status quo, take risks, and explore innovative ways to solve problems and push boundaries.

10. Legacy is Built Over Time

Maggie Smith’s career didn’t peak with one role or one decade—it was the accumulation of years of hard work, consistency, and dedication to her craft. Leaders must remember that success and a lasting legacy are not built overnight. It’s through sustained effort, resilience, and integrity that true leadership is cultivated. Like Maggie, leaders should focus on the long-term impact they want to leave behind.
