Poll: What age did you feel like you actually knew what you were doing as a dad?

My oldest is 8 and I still feel like I'm winging it 90% of the time. Occasionally something goes right and I think "oh maybe I do know what I'm doing" and then the next day I forget about a school project due that day. When does the confidence kick in? Or is this just permanent? Asking so I know whether to expect an actual answer or just solidarity and commiseration lol
