I really don't like the sentence "Tell me about yourself" because I feel even I, am still getting to know myself. I also feel like whatever I say may not represent the full picture and worst of all, that I may leave out details about myself that I may not be proud of; making me appear perfect.
Guess you have a sort of inkling about the kind of person I am now.
Nonetheless, I could say a few things: I enjoy talking about my interests. I've learned that tying good habits to my personality makes me a better person so I am a runner instead of someone who exercises, I'm a punctual person instead of someone who keeps to time. You get the jerk.
I'm an optimistic realist...
That's all that came to mind as at the time I wrote this but there's a whole lot more to know about me. Who knows, maybe that book will be written someday. Amen?
