I turned 18, 5 years ago. I'm obviously the oldest and most adult I've ever been. I always thought I'd be a proper grown-up as soon as I was in my twenties, and I sort of am. But, I've only been an "adult" for 5 years so I still don't really know what I'm doing. I don't really know where this revelation has come from but it's made me feel way more comfortable about where I am in life. I am so young, I certainly don't need to have everything figured out yet.
This doesn't mean I have an excuse to slow down though because I refuse to ever slow down my plans and my life for any reasons that aren't of complete urgency. I have big plans lads, and nothing can stop me.
And as an adult, I will be continuing to wear pinafore dresses for eternity.
