Time to see how I did!
Cubing goals:
2x2: Get a really good single so people will think I'm cool.
Daaaang, it happened! 1.44 single with a stupid scramble.
3x3: Get a sub-10 average with sheer luck, make semis.
Nope.
4x4: Sub-45 average, sub-40 single.
Lol, I missed 4x4 because I forgot it was happening.
5x5: Sub-1:35 average, sub-1:25 single.
No, but kinda close with the average.
6x6: Sub-3:10 mean, sub-3:00 single.
Got the single but not the mean.
7x7: Sub-5:00 mean, sub-4:50 single.
Not even close.
Pyraminx: Sub-2.95 average, sub-2 single, podium in finals.
Ooooh very close. 2.98 average and 2.02 single, and 8th in finals because of shaky/numb hands. 
Megaminx: Sub-1:10 average, sub-1:00 single.
Got the average, not the single.
Skewb: Get a good single for once, beat Daniel Karnaukh.
Both of these!
Square-1: Hope for lucky scrambles.
I hoped, but I didn't exactly get them. 
Clock: Sub-16 average, sub-14 single.
Both of these (by a long shot)!
OH: Solve the Rubik's Cube with one hand.
Did it!
3BLD: Any mean whatsoever.
No...
Messed up the last solve.
FMC: Some decent single, PB mean.
Nope.
Non-cubing goals:
Complete all summer homework on the plane ride.
About half of it.
Get there on time.
Did it!
Hang out with friends a lot.
Yes sir.
Ride the elevator frequently.
You bet!
Overall, I'm really happy with how Nats went. I'm still kind of annoyed about my results in Pyra finals, but there's always next year.
