Your amount-of-luck is the surface area of a rectangle. A side is the interestingness of what you do, B side is how many know about it. The bigger the rectangle, the more opportunities you get.
This is how you get opportunities when you aren’t even in the room. Someone says ”Oh yeah I know <ksec>, they’re doing cool things X in the area you just mentioned an interest in”. Or ”Oh yeah for problem Y, you should ping <ksec>, they’re the expert”
Need to steal that.
And is this a reason why Twitter, Social Media, and self branding on the internet are so important? Since it is all who knows you?
