I like commenting on things.
Do you try to hold back on your comments?
No, I don't hesitate to say something even if most people think it's horrible, I speak my mind.
It is okay to have an opinion and tell others your thoughts. But it is annoying to others to blurt out anything just to seek attention from others. So you should think before saying the first thing that comes to your mind.
I can't stop that, it is how I am.
You can stop it with time. Keep trying to work on yourself so you are not annoying everyone you are around.
