Replace "old" with "sad". Then add "and old" after "sad". Rant about life below:

Last night, lying in bed, trying to fall asleep before 1AM, I got to thinking... <-- That's a bad thing to do though, because then I can't fall asleep. Too much to think about. I can never seem to match my age with my life. WHAT DOES IT MEAN TO BE 16? Well, I didn't really care much about my age...and I probably should stop. I only use age as an indicator for how much longer I have to get some substantial accomplishments in my life. Good/Bad? I dunnoooo. But uhh, not that accomplished yet.

I always imagined 16 as being at the peak of your high school days, lots of drama, lots of fun, etc. And uhh...taller than 5'2" (Fine. Back in the day, there was a lot less pollution, so their growth wasn't so stunted T__T). MY 16, however, is one where I have to decide on something to study in university, which university, whether or not I can fulfill the requirements of the chosen program, how I can fulfill those requirements, and so on. It's tough T____T.

(This rant is going absolutely nowhere...)

At 16 . When adults ask me what I want to go into, and I tell them I don't know, they just say, "Oh well, you're still young." Uhh, come to think of it...It's probably that they don't know how old I am... ANYWAYS, I've finally realized that being "still young" has nothing to do with anything. It's more like, I'm entering my last year of high school; and SO, I should have some ideas about uni.

Conclusion: Completely disregard age.
I won't say - "At 16, I'm supposed to do THIS, but not THAT because everybody does that when they're 17."
I will say - "This is my last year of high school, I need to get into THIS university so I can be THIS when I'm an adult."
Tadaaaa~ Therefore, age means nothing.

All I have to do after that is figure out how to cut corners in uni+grad school so I can get out into the world as soon as possible. >
