The worst advice I've ever heard for product teams:
"Move fast and break things".
I've watched it bury startups in features nobody asked for.
Speed feels like progress. Being able to close a ticket feels like a win.
But ticket crushers (devs who just clear the queue without asking why) leave a mess behind. Fix one thing, break three others. Repeat.
If you don't understand why a ticket exists, you shouldn't be closing it.
I'd rather a developer move slow and think two steps ahead than crush tickets all day and leave a mess behind.
Methodical beats fast when the thing you're building has to hold weight.
The work that looks slow today is the work you don't have to redo on the next PR.
