We really are living in the era that all this sci-fi literature and cinema was centered around, but it's not anything like what we envisioned it to be. It's almost like there's too much choice.
I'm not advocating the strenuous life for everyone or trying to say it's the choice form of life. Anyone who's had the luck or misfortune to be an athlete has to keep his body in shape. The body and mind are closely coordinated. Fattening of the body can lead to fattening of the mind. I would be tempted to say that it can lead to fattening of the soul, but I don't know anything about the soul.
The first thing I do in the morning is to make my bed and while I am making up my bed I am making up my mind as to what kind of a day I am going to have.
