Whether he intended it or not, he was teaching me the great lesson his years of struggle had taught him: Don’t let your head get lost in the clouds. Pay attention to the details, to the nuts-and-bolts realities of things. You can’t build a life on a foundation of dreams and wishes. A good life isn’t plucked from the sky. You build a life up from the ground, with hard work and clear thinking. Things make sense. There are rules and realities that will not change to suit your needs. It’s your job to understand those rules. If you do, and if you work hard and work smart, you will be all right.
