What's one founder habit you thought would matter a lot, but ended up not mattering much?

When I first started building, I thought I'd need a perfect system for everything. The perfect task manager. The perfect morning routine. The perfect folder structure. The perfect productivity setup. I spent way more time thinking about how I was going to work than actually working. Now I'm realizing a lot of things I thought were important barely move the needle at all. Some days the only thing that really matters is shipping something, replying to users, and showing up again tomorrow. I'm curious if anyone else has had the same experience. What's one founder habit, tool, routine, or piece of advice you thought would matter a lot but ended up making almost no difference?
