Hehe, personally, I'm probably not the best at what I do, but I sure as hell try to be. Playing video games is one of my specialties, so when I play, I play for fun, excitement, and to show what I can do =:D.
In FFXI, I've been told by my closest friends that they wouldn't have any other BLM than me, and that I'm one of the few ones out there that has a decent Freeze burst macro. Also, I do a damn good job at bursting on skillchains, even when I play on 56k and lag spike just as the chains start @_@. With that said, i guess you could say I'm pretty good at being a BLM ^^.
Non-game related though, I know I'm really good at being funny. Making people laugh is one of the things I live for, and it makes me happy to see my friends crack smiles or completely burst out laughing at what I say and do =:D. I'm better at 'spur of the moment' type jokes though, or improvisation type stuff. I can't plan material ahead of time for the life of me XD.
