Read outside of your field
I found this great post called Real World VS. Book Knowledge by @morganhousel. The article reminds us that book and real-world knowledge have both upsides and downsides. That neither is necessarily better than the other.
But my favorite part is at the end when @morganhousel shares ways of processing that duality and improving our understanding of 'these two worlds'.
The final advice is to read outside of your field.
