Truth —more precisely, an accurate understanding of reality— is the essential foundation for producing good outcomes.
I want you to work for yourself, to come up with independent opinions, to stress-test them, to be wary about being overconfident, and to reflect on the consequences of your decisions and constantly improve.
[...] Your goals will determine the “machine” that you create to achieve them; that machine will produce outcomes that you should compare with your goals to judge how your machine is working. Your “machine” will consist of the design and people you choose to achieve the goals...
Think of it as though there are two yous—you as the designer and overseer of the plan to achieve your
goals (let’s call that one you(1)) and you as one of the participants in pursuing that mission (which we will
call you(2)). You(2) are a resource that you(1) have to get what you(1) want, but by no means your only
resource. To be successful you(1) have to be objective about you(2).
Most problems are potential improvements screaming at you.
