There's a great article on Vox about how this uber-capitalist mentality--that you need to be Improving Your Use-Value every second of your life--is pointless, self-defeating, and miserable.

You can't go through life obsessed with raising imaginary numbers in hopes of getting some vague existential prize at the end. Because you won't.
You're not going to wind up like Arnold Schwarzenegger. You're just going to be frustrated, depressed, and constantly disappointed with yourself. You'll alienate the people around you, and your relationships will suffer.
You'll suck all the joy and poetry and beauty out of life, and for what? Another goddamn listicle on EIGHTEEN WAYS TO SUPERCHARGE YOUR PRODUCTIVITY?
