I've done a lot of "public prestige building." But the things that actually got me to this point, quickly, were:
1. Being close to the money within the companies I worked at
2. Keeping up a habit of meeting and talking to people 1-1
I realized about five years ago that I enjoy meeting people 1-1 much more than publicly writing and speaking. You can say things a lot more honestly 1-1 without worrying about who might see it one day, and it makes me feel better than trying to turn myself into a public spectacle.
With folks getting much more comfortable meeting remotely, this has become even easier. I've met some great folks who I now have outside-of-work relationships with as well. Usually all it takes is asking someone if they'd like to meet again in three months or so; and, after a couple of these, asking them if there's someone they wouldn't mind introducing on a no-agenda basis.
I also genuinely don't have an agenda for this, other than that I like meeting people.
However, I also find this opening statement telling:
> Most months I get at least one email from an engineering leader who believes they’d be a candidate for significantly more desirable roles if their personal brand were just better known.
Most of us are bad at self-introspecting about our careers. I suspect a lot of the folks thinking this way need more than brand recognition, because this perspective (to me) would be a potential sign of lack of maturity that I would want in a senior leader. (This is a complex topic, and one that I think needs to be handled on case-by-case basis rather than recommending general approaches.)
