Key quotes

· 5 pulled
The biggest shock of my early career was just how much code I needed to read that others wrote.
What I quickly learned is that you don't have to understand a codebase in its entirety to be effective in it.
I had a hard enough time understanding my own code.
The idea of understanding hundreds of thousands or even millions of lines of code written by countless other people scared me.
So rather than tell, I want to show.
