Becoming a thought leader is about providing your unique and valuable expertise to people at no cost to them. There’s obviously nothing egotistical about that.
Of course this is not philanthropy either. As this post describes, there are benefits that come with becoming a thought leader, including many direct positive impacts from a professional or business point of view.
We can then go further and ask: can everybody become a thought leader?
To me, it’s down to expertise. If we believe we all have expertise, then we all can show thought leadership. From what we say, from what we create but also from what we read and curate.
