Those small details...

"And say to yourself here-and-now, here-and-now, here-and-now. 'Where am I?' 'Here'. 'When is it?' 'Now'. Take an object or a person. Anybody. 'Here and now I see a person.' 'Here and now I see a man.' 'Here and now I see a man sitting on a chair.' Take me, for instance. Don't let your mind wander. 'Here and now I see a man in a brown suit. Here and now I see a corduroy shirt.' You have t narrow it down, one item at a time, and not let your imagination shoot ahead. Be in the present. Grasp the hour, the moment, the instant" (pg 86)

I believe this passage summarizes the whole purpose of the book. Although it isn't the first time this type of thinking is mentioned, it is the only time when it is truly emphasized and developed upon. The whole book describes one day in Wilhelm's life where everything goes wrong and he starts facing all his problems. In my opinion, the character Dr. Tamkin plays an important role in the book, he is the only one who is willing to give Tommy advice that is really worth knowing. He constantly tells him to live in the moment. To seize the day. 

Also I think we should all learn from this. Currently, we live in a world where every things moves fast, where life has to be lived a a fast pace, and the only way to keep up is by adjusting ourselves to this change. Although this type of lifestyle be beneficial sometimes, it also harms us. We fail to acknowledge those small details in life that make us happy, those small things that we take for granted are the ones, that without knowing it, make us really appreciate we are very lucky to have the many things we have.
