The way I read the essay is different stages in life require different perspectives. All night hacking sessions on Red Bull and ramen work until your mid 20s.

The way I read the essay is different stages in life require different perspectives. All night hacking sessions on Red Bull and ramen work until your mid 20s. In your 40s it'll kill you, quick and you're knowledge or ability will not be any better for it. You need to spend time to sit down and absorb the knowledge. Games like golf and I don't know skeet shooting show how you can do more with less. However, that doesn't mean the foundation you built in youth with intense practice or an unforgiving drive to achieve is now worthless. Rahul can say "you are not running out of time" because he stepped on the pedal damn hard. To each their own. I'm pretty sure that if Rahul went bankrupt tomorrow he'd be back to his 17 year old self hustling with everything he's got but if he did that now he'd be putting more at risk than he has possibility to gain.
