Blogging and watching what you type.

I never knew why i wanted to start a blog. Maybe to tell what's on mind. But then again, i'll be sharing my thoughts with the WHOLE world. I mean, if this blog gets to the whole world ?
I guess, i don't know why i Really got a blog ? My sister told me to make a blog so that i could keep my mouth shut and just type type type. But then i realize, everytime i make a post, i'll be too lazy to finish it. And therefore this post won't be finished. HAHA , cause i'm TOO lazy : )
