Well I suppose I will tell you the three facts about myself: what I like, what I don't like, and what my ultimate goal is.
I like a few things. If I had to pick the best, I suppose it would be reading. Although I've caught up on the Icha Icha saga, I haven't memorized it. I've even considered writing some fan-fiction for it... but I could never pick up the gauntlet that Jiraiya-sama left behind.
I don't like having to repeat myself. Yes, sometimes what I say can be hard to believe, but you must understand that I am not always what I appear to be. Also, if I tell you something, and after three seconds you look at me and say "huh?" I will kill you.
Someone once asked me what my ultimate goal was. I told him that it was to become a powerful ninja in order to protect the ones I loved. So he challenged me a to race around Konoha in order test my strength. I beat him. A few weeks later (after some hard core training) he challenged me again. I beat him. The next day, he challenged me to a handstand contest. I beat him. A month later, he wanted to see who could run through a rainstorm while getting the least wet. I beat him.
Since then, I have worked hard for my ultimate goal, and he decided to adopt his own. Our eternal rivalry exists today, though I encourage him to set it aside for a goal with less humiliation attached.
