I don’t get this critique. Obviously if you are capable of a high-priority path you should take it, and it needs to be clear to people what those are. If you’re not, you do the next best thing. The point is to do the best YOU can do. Not some theoretical person that has your name but a completely different set of abilities. When I was a kid I wanted to be President. Now I am resigned to the fact that that will never happen, but I don’t feel excluded when a Presidential election is in the news day after day.
I also think it’s important to be honest with people about their probabilities of success. I could spend all my time running Vermin Supreme-style campaigns for President, because being President is the “best” thing, or I could make use of the more limited political talents I actually have and maybe over my career be pivotal in one or two changes to the law in my area of expertise by a) having an area of expertise, and b) being humble and developing good relationships with my Senators/Congressperson. But I have to understand the ways I fall short of the typical viable Presidential candidate in order to understand why the second option is better for me.
