Changes

Was going through my previous post finding something while i discover something, i changed!
Changed from someone who only blogged words to adding pictures, and feelings and even some meaningful lines. Changed from someone who only blogged once a week to everyday, then back to someone that blogged once a week again.
People do change eh? Sometimes a change is a good thing, but sometimes it ain't a good thing, ppl will say "that's life, that's humans". But i can't really think of why human change into someone bad? Changing into a good person to make life more meaningful, but why change into someone bad? Even, what makes a person want to change be it better or worse?
There's sure something, but i think that every one's answer will be different, there ain't a accurate answer. I think it just reflects how you think and what kind of person are you.
