See, when I was in school, they didn't teach fail fast and if anything they told you not to. Nowadays, we have moved past that nonsense. I gave it a shot about a year ago, and it has made me a better programmer. I am not going to sit there and count braces, but things are a lot easier when you get the error cases over with and out of the way.

There are always going to be exceptions, but I have personally found a lot of value in using 'fail fast', and making more smaller methods that say what they do. I am not always great at that second part, but it is a process. As someone with severe ADHD, it has made it a lot easier to work through problems. Sure, you can end up with more lines of code, but who cares. Compiler should be optimizing most of that shit out anyway.
