Beliefs might be correct (or not). They might be useful (or not).
Optimize for useful beliefs.
Useful beliefs help you win.
Useful IS correct.
Correct may or may not be useful.
Useful reveals correct.
What do you want? Go. Get it. Your beliefs will quickly reveal themselves to be useful (therefore correct) or not.
And when you have what you wanted, the correctness of the beliefs that got you there will be immaterial.
Except.
They will be the building blocks for your next adventure.
But not the beliefs—tested and proven by reality. Those are not the building blocks.
The ability to aim, to head straight for the prize, and to adjust your beliefs to whatever is needed to accomplish your goal.
That skill—learning while running the mountain path—is the true building block for your next adventure.
