What exactly is tangible about this advice? The only thing tangible about it is that everyone is going to be trying to analyze everyone else to see if the fit into the mystical buckets of A players versus B players.

Seth Godin sometimes has interesting insights but this type of stuff is just selling self help advice that leads to nowhere. Just do what your interested in and think your good at - stop trying to put yourself and others into meaningless buckets, people are people, not A vs Bs.

It's it, by definition, impossible for everybody to be above average? Wouldn't that just constitute the new average?

The title is poorly worded. The actual statement is along the lines of "if you are settling for average, it is a sign to move on". Being average is the problem, not striving to be better is.

Right, if you are devoting time being average and not growing at X when you can be grow and be extraordinary at Y, it's time to move from X to Y.

" 'Never Quit.' What a spectacularly bad piece of advice. I think the advice giver meant to say 'Never quit something with great long-term potential just because you can’t deal with the stress of the moment'. Now that’s good advice."

That's fantastic.

Effin middle class. What a waste of oxygen.
