Don't have dreams, aspirations. Dreams are just another banal experience, only not yet realized.
Better yet, have dreams but leave them be. Let them be dreams, let them stay a golden land of idealism to which you mentally flee when caught in the midst of your current mundanity.
Don't chase them, don't turn your dreams into your routines.
Place them upon a shelf and marvel at them with an enormous and writhing sense of what if.
Enjoy that feeling, revel in the wander-thought for that is the truest form in which dreams exist.
