Most people underestimate the decisive impact of the environment on output. Many believe that success relies on personal talent, self-discipline, motivation, and 'persistence.' While these are certainly useful, they are not the primary cause.
The real leverage lies in two things:
who you work with and what you choose to do.
Naval says: 'Work with hardcore people on hardcore things.' Behind this statement is a harsh but true rule:
Mediocrity is contagious, and excellence is also contagious.
Your standards are rarely developed in a vacuum; they are more often 'calibrated' by the people around you. The circles you associate with long-term shape your long-term return curve.
What is meant by 'hardcore people'?
Hardcore people usually do not shout, show off, or perform.
They do not rely on social media to create personas, nor do they use 'I'm very busy' to grab attention.
Their 'harshness' is silent, persistent, and even a bit uncomfortable:
They are committed to facts rather than emotions.
They care about precision rather than 'close enough.'
They pursue results rather than 'I have already worked hard.'
They can see details that others overlook.
They cannot tolerate logical flaws, loose execution, or half-finished results.
Most importantly: they are even harsher on themselves.
After being with such people for a long time, you will become unaccustomed:
Your excuses will start to fail, and your 'close enough' will be immediately exposed.
You can no longer be moved by intentions and processes; only results can settle accounts.
This discomfort is actually a signal: it indicates you have entered the right trading hall.
Hardcore people will simultaneously raise your lower limits and open your upper limits.
What is meant by 'hardcore matters'?
Hardcore matters are those that do not follow shortcuts or easy paths.
They require depth, patience, and long-term focus. Their characteristics are:
Failure is the norm.
Feedback is slow.
Progress is nonlinear (like a yield curve, not linear growth).
For example:
Entrepreneurship: creating something new from 0 to 1.
Scientific research: difficult problems without standard answers.
Craftsmanship: a ten-year start, twenty years to form.
Complex thoughts: cannot be compressed into a single slogan.
Hardcore matters will force you to upgrade:
Simple problems reward 'being able to do things.'
Difficult problems reward 'being reshaped.'
It will change your cognitive structure, your character, and your tolerance for uncertainty.
Most people avoid hardcore matters because they directly hurt their self-esteem:
You will appear foolish, make mistakes, look bad in front of others, and be educated by the market.
But this is precisely its value: it brings you closer to reality.
The key is the combination: people × things.
Hardcore people doing simple tasks will become bored and cynical.
Ordinary people doing hardcore matters will be overwhelmed by pressure and fluctuations, ultimately quitting.
But hardcore people doing hardcore matters will enter the 'compound interest zone':
Effort does not evaporate; it accumulates.
Standards do not need to be pushed by managers; they naturally maintain high levels.
Learning speed increases because everyone takes it seriously.
You don't need to rely on motivation; you will be driven by the quality of your mission and your peers.
This also explains why Naval emphasizes:
Play long-term games with long-term people.
Hardcore people do not need to be supervised or persuaded about the meaning of work.
They have already made commitments internally.
This alignment is rare and valuable.
Cost and return (traders understand this better)
Choosing this path usually means giving up comfort early:
Smaller teams, less security, fewer shortcuts, slower external recognition.
But the returns are asymmetric:
What you gain is skill density, aesthetic/taste, judgment, and a confidence 'based on reality rather than applause.'
Over time, you will find that you are not filtering for 'intensity,' but for 'integrity/honesty':
Hardcore people care about doing things right.
Hardcore matters force you to face reality rather than live in fantasy.
This set of combinations will peel away self-deception layer by layer.
Three self-checks (like a review)
If you feel stagnant: first look at the people around you.
If you feel you are not growing: then reconsider if what you are doing is challenging enough.
If you feel progress is slow: ask yourself—are the demands of people and problems high enough?
Life is too short; don't associate with those who don't care, and don't waste time on unimportant issues.
Seek hardcore people.
Do hardcore things.
Everything else is noise.
