Do I need to visit a shrink?

It was just this Monday when I was wondering that I haven't been using my brains enough. Its true that the normal human being uses about 10 percent of his brain, Einstein (not-normal by all standards) used 13 percent of his brain. I am probably using 0.097 percent of it considering the periods of time I do nothing. Here is an example. I sat for two hours in front of the television doing nothing except changing channels. Nothing on TV could hold my attention for more than 5 seconds. I have to confess though that my brain showed signs of activity on seeing the advertisement for 'The making of the Kingfisher Calender 2010'. But for the rest of the time, I was as good as a vegetable. It wasn't until I could hear my remote yelling 'Stop poking me you *&^%$#@&!' that I came out of my stupor. I called up a friend and discussed the lack of use for my brain but she had better things lined up for her brain so I had to hang up. 

I once wrote a post about how an empty mind becomes a devils workshop. It was today that I realized it. When you have nothing productive to do then your brain starts cooking up things. For example, if your friend is not in a great mood and you happen to call him/her up then your brain is going to assume that it is because of you that his/her mood is so rotten. And then begins the chain reaction of negative thoughts. It starts off with analyzing the things you said to this friend and finding fault in them. If you can't find out any particular fault in your words then you move on to words said in the recent past, not so recent past, past, past past and then ancient history. By this time, you have ruined your mood as well. Then comes anger. And then you can be sure that you are on the verge of losing a friend...and your phone if you happen to slam it on the wall in front of you. 

This was just an example. yes, it happened to me, not so long ago. There are more examples but will share them later on. What I wonder sometimes is this; is having an empty mind better than having a mind with shitty thoughts? Or does having a mind with shitty thoughts follow the stage when the mind is empty? And if that is the case then how to find something to occupy the mind with and even if we do find something to keep it occupied, what are the chances that it will not be filled up with shitty thoughts about the thoughts which have finally occupied my mind? Getting my drift?!...

I am sure the last paragraph proves how my thought process works sometimes and revels the level of vulnerability of my brain to the hands of the Devil. Which is why I wonder sometimes whether I need to see a Shrink or not.
