You need to elevate your intellect to metacognition. Learn how to learn. Learn the difference between generalisation and domain knowledge. Domain knowledge can always be looked up in reference material (though memorising as much as you can is good too because deeper domain knowledge will give you a greater perceptual experience). I dont know if there's a canonical source on how to do this, but I have found studying mathematics and pure logic continues to give me a toolset I can use to decompose reality into atomic constituents. Accept you wont learn it all, you are limited in time and space, and use your knowledge for good, try and do the greatest amount of good for the greatest number of people you can.
