Of sober thoughts and mindless dreams

Here I go again, my fingers punching the letters that of which make this sentence exist. Had my mind be thinking of something valuable then I would've written it already. I've been thinking again, lately ( thank god i found time to write it down ) about what I wanted to do in life. What if I don't really wanna do something in life, what if I want to be something (or someone, rather ) Signs of being bipolar show as I write. But then again, how would I ever know.
