Yeah, this was something I recognized about myself in the first few years out of school. My brain always wanted to say "all of this is a mess, let's just delete it all and start from scratch" as though that was some kind of bold/smart move.

But I now understand that it's the mark of a talented engineer to see where we are as point A, where we want to be as point B, and be able to navigate from A to B before some deadline (and maybe you have points/deadlines C, D, E, etc.). The person who has that vision is who you want in charge.

Chesterton's Fence is the relevant analogy: "you should never destroy a fence until you understand why it's there in the first place."
