#3 hit hard. You can edit a bad page, but you can't edit a blank one.
I've wasted weeks overthinking architecture for things I'd never built. Shipping something ugly and learning from real feedback taught me more than any amount of planning.
Also #6 is underrated. Early on I thought good work speaks for itself. It doesn't. Took me years to realize decisions happen in rooms I'm not in. If no one can explain your impact when you're gone, it doesn't exist.
Thanks for sharing this.
