those who do too much somewhere do too little elsewhere - Nassim Nicholas Taleb

In a long career, I've (almost) never seen anyone get rich while employed (via bonuses/stock options, as w/bankers, CEOs, & rich slaves), & subsequently also make money on their own, in self employment. If you can't make it on your own, it's.

Let me insist that erudition is important to me. It signals genuine intellectual curiosity. It accompanies an open mind and the desire to probe the ideas of others. Above all, an erudite can be dissatisfied with his own knowledge, and such dissatisfaction is a wonderful shield against Platonicity, the simplifications of the five-minute manager, or the philistinism of the overspecialized scholar. Indeed, scholarship without erudition can lead to disasters.

Having an assistant (except for the strictly necessary) removes your soul from the game.
