I believe having a vision in mind, a goal let's say, is a good thing. Unfortunately, so many of us are blinded by the greatness of our vision that paralysis and inaction sets in. What I try to do is focus on the individual steps, the moments if you will, and let them lead one to the next. The vision that eventually appears may not be exactly what you had in mind, but it will be the right one for you, because you did the work and you took the necessary action.
