It’s worth hanging out around work of people that do it because they are true to themselves. Music, programming, business, relationships — all of these can be done with a hidden agenda, or honestly for the pure value of doing it.
I really enjoy working systems. I enjoy watching how a well-designed mechanism runs with little human input, no unintended outcomes, no unhealthy incentives and no wasteful products.
Poor morals, absence of dignity, interests based on fear and greed — these are leaks in the system. It’s like trying to heat a room with an open window. These systems are corrupt.
You can judge the tree by its fruit.
The best indicator I found so far to see if a person is true to themself: try finding out what the person does in their free time.
