Back then it had more to do with titles, badges and positions. Now I think it’s all about making a difference; it is about influencing people or situations towards a better outcome.
Leadership is adding value. It isn’t just about authority or having a title, it’s being a carrier, a burden-bearer, a load-lightener.
Leadership is functional and practical, and is essentially nothing to do with age, gender or background.
By the above definition there are many more leaders out there than you or I previously thought, which is good news. And you’re probably one of them!
