From corporate drone to stay at home dad and I don't recognize myself

Quit my job 8 months ago to watch the kids while wife works. Everyone said I'd hate it but honestly I'm in a completely different headspace now. Used to define myself by my job title and paycheck, now it's like that guy doesn't exist anymore. Miss the adult conversations and feeling important at work, but I don't miss the anxiety or the commute. My kids actually know me now instead of just the tired guy who shows up at bedtime. It's weird how much your identity is tied to your career until it isn't.
