To write for readers is quite different. To just write and express is different. When you know that a lot of people will be reading and they will be judging you on the basis of that, it steals away the originality of your thought. Nobody wants to look bad in front of others.
When I write here I know that not many are reading and I feel free. I write more often in my personal diary here and that's the best dump of my emotions and thoughts. I am true to myself.
