Different people gage being a grown up in different ways. This is how I gage:
In the last year....
I went through a period of unemployment without having to seek assistance with my financials.
I stop waiting for someone else to care as much about my birthday as I did, and threw myself the best 25th birthday party I could imagine.
I went on a fabulous vacation (and crossed an item off my life list) by going to the Winter Olympics, just because I wanted to.
I turned 25 (lower car insurance rates).
I test drove a car for the first time, and sat through the "we want to get you in this car" speech without once being tempted to go for it, even though I really liked the car.
I got a job that I actually get excited to go to everyday.
I moved without my brother's truck or friends truck, but not without my brother's assistance.
I threw my back out.
I started to enjoy the taste of coffee for the first time.
What made you say- I'm grown up now?
