Being a Race Car Driver
Race car drivers want to drive cars at 300 km/h around a track. To win.
To get there, they have to be able to do other things: get in physical shape, know their way around an engine, build a network of partners, etc.
But a driver who did nothing but physical training, day after day, wouldn't become a driver: they'd become an athlete.
One who cared only about mechanics would become an engineer or a mechanic.
As for the one who puts all their time into their network, they'll end up an agent or a manager.
Never lose sight of the source.
What you do now is what you'll do later. Preparation can become your whole life.
The whole game is finding a way to do it now, even when the conditions don't seem to be there.
