Today I realized that a work is the strange thing.
Sometimes you are needed it; you deliberately search for it, and if you finally find your occupation, then it could make you happy.
You can spend more time in doing something useful on your job, and you believe that it equally makes you useful as well.
But sometime you find that your head can't accept any thought about work at all.
There is the one desirable thing that you want is to be as far as possible away from your work.
And even a continous break doesn't help.
You need a more powerfull treatment to handle with this.
As for me, the most advisable way to achive expecting comfort of mind is a diving to amusements.
Then you can go back to work.
