Not Ready for Primetime

Just busted out of the tournament in 1370th place out of 1594.
I caught A-Q on the first hand, then Q-Q on the third and was big stacked. The guy to my left kept raising and never folding, the only hand he turned over was J-6. So when I got in a pot with him I put him all in, hoping he'd have junk and fold. He had pocket jacks against my weak ace. After that I got caught with another weak ace and went all in after an ace hit on the turn, trying to steal the pot, unfortunately I got called by A-K.
