When you are in a bad mood, ask yourself often, what do you think you can't think about?

When you are in a bad mood, ask yourself often, what do you think you can't think about? What do you think? If you feel unhappy, look out of the window, have a limitless view, look at the vast expanse of the sky, and learn not to close the door. Life has no despair, only think not, life has no end, only can not see. New reason why science is beyond dreams, a short duration of time. To turn the mind is to hope, to return to the head is the next life. ​​​​
