Working a job is the fastest way to destroy a person.

The essence of employment is that you "wholesale" your life and time to a company, which then "retails" your labor output to the market through its organizational structure.
This means you lose the most important lever of wealth.
Even if you work 24 hours a day, your returns are capped and only grow linearly.
But the marginal profits generated by your labor should grow exponentially, yet they all belong to those who control the means of production.
You're using your scarcest asset—non-renewable time—to exchange for fiat currency that continuously depreciates.
Working makes you appear busy every day, but in reality you're just repeating high-frequency muscle memory at a lower dimension.
What's worse, your brain's computing power gets depleted daily by countless meaningless meetings, careful wording in reports to superiors, and managing interpersonal boundaries with colleagues.
The most direct consequence of this is:
When you drag your hollowed-out body home at 8 PM, you have no remaining energy for deep learning or side hustles.
You can only numb yourself passively by scrolling short videos to produce cheap dopamine.
The result of using three years of experience over ten years is—it completely ossifies your cognitive boundaries and causes you to lose the ability to handle the complexity of the real world.
