Little by little you must train yourself for life, for happiness. You probably received a college degree that you spent years working for, and you thought that happiness would be possible after you got it. But that was not true, because after getting the degree and finding a job, you continued to suffer. You have to realize that happiness is not something you find at the end of the road. You have to understand that it is here, now.
