There was some good discussions from the All-In podcast talking about actors and writers, but also more generally about work and purpose.

Some may argue that acting also follows the power law there the winner appear to take all (winner take-all) and the 10000th actor can barely make a living.
This also applies to blogging as well (such as this author wondering why he probably makes a few cents per hour writing this).

Obsession level :

One other good point they made, is if someone wants to pursue a career where the dynamic of power law exists, they need to be obsessed about it. As much as they can't help it but work on pursuing their craft. This is how they can commit up to 60-70 hours a week, and it doesn't feel like much.

People often tend to look for a profession to pay the bills and have a "work/life balance". There is nothing wrong with this, but there is also another class of work where someone would willingly want to sign up to be the best at what they do (and push their craft to the limit). Those are the NBAs, Hockey Player and entrepreneurs of this world.
Nobody will force someone to be in the wrong class of work (work/life vs performance), but having the choice allows to optimal growth and more importantly, provides the choice to the individual.

Knowing where the bar is :

One good point David Sacks made is that people shouldn't compare themselves with the worse person who "made it" but rather compare themselves with the best person who hasn't made. Since those are the real competition.

Note that investment also could be considered a power law business, especially when it comes to hedge fund managers. The value creation of hedge fund over a period of 10+ years still remains to be seen, with a few rare exception (like Renaissance Technologies). Successful fund managers are all but obsessed about which stocks to buy.
