I’ve had a similar approach, so I can give my take. You can read the advice cynically or genuinely, and either could be true. It depends on the organization. If you’re working somewhere that this can be taken at face value, you’ve got a good gig.

For me, I make sure I work in an industry that benefits society, and I make sure I work for a company that fits the spirit of bettering society. After that, a lot of the rest takes care of itself. Does that limit opportunities? Sure - it eliminates a number of government agencies and most publicly held companies. That still leaves a huge amount of space. By making sure I’m working somewhere with a clear mission I agree with, what makes the boss happy is likely to line up really well with what I’d want to do anyway.

Billing mistakes default to benefitting the customer, production incidents are as transparent as possible, consistent long term views on how to build a product and business (yes, you still cut corners when it makes sense, but you build a strong foundation to let yourself move really fast at the right times), etc.

Another benefit of consistently getting things done without drama - you end up with a lot of autonomy. When you see something that needs to get done, or a project you’d like to be involved in, things just seem to line up.
