I was wrong, there is no time where you are an adult, its a constantly evolving state.

I thought I was an adult when I was in college, I was wrong.
I thought I was an adult when I was married, I was wrong.
I thought I was an adult when I became a doctor, I was wrong.
I thought I was an adult when I had my first child, I was wrong.
I think I'm an adult now.

By definition, I've been an adult at all those points, but I've changed so much as a person, improved and matured, that I can look at my past 'adult' selves and think 'god what a stupid kid I was'.
