Take account of the plethora of opportunities available to you; use your imagination. The liberty to be oneself is of unsurpassed preciousness. What threatens it is big government, criminals, poverty, war and similarly debilitating conditions in which a person or circumstances rule over a person, making him unable to fulfill himself in his life. This liberty is a crown jewel in Western political theory. It is an object of devotion in the eyes of the American Constitution. Imagination is funny, but a liberty from governmental, criminal and poverty-induced regimes of behavior are its siblings. They thrive together. One discovers a course for one's life which is among the best things one can do with one's liberty, in view of one's preferences, talents, and circumstances. (There is something deeply human and personal about the value of liberty, even though liberty itself is a pretty starkly simple concept.)
The free human spirit loves the imagination. It makes clear for that spirit which paths make sense. Imagination sees how things fit together under various scenarios, so that we can judge which path to prefer. It should go without saying that logic and empirical evidence are also important in choosing a path of action or way of life. But imagination lets you see. It is like the illustrations, figures, photos and other visual bits in a book, only it's not limited to the visual faculty alone.
You need to think through your own talents and where they might lead. What do you have to offer that people need? See whether you can imagine it. What would you prefer to do over the course of you life? See whether you can imagine that, as well. In each case, you need facts about people, inferential powers, and the imagination to project a way of dealing appropriately with the former.
There should be no holding you back if you can only get a good hold of yourself in that place, where you love yourself and feel powerful enough to be yourself splendidly because the circumstances are such that you are free. This is the key blessing of the American political system. The American people could cease to care about this only if they forget forget this. Don't forget it. Dig deep within yourself. You have a reservoir of talents and intelligence and drive to tap into. You must protect the political circumstances which protect your free exercise of the right to do so.
Kkeep close tabs on the facts about human beings and yourself in particular and the facts about your circumstances. See whether you can understand human nature generally and also your particular character and circumstances. The American dream is closely tied to reality. It is not unmoored but free.
