To dream, to wish, to hope - all those are good and worthy emotions but they're not worth much without dedication and the hard work that goes with it. That was the lesson of the Rocket Boys. It isn't the smartest who necessarily gain their dreams. It's the people who roll up their sleeves and are willing to sweat a little who ultimately succeed. It's simply one of those axioms of life that must be recognized.
Perseverance equals success.
But all should not be work, even passionate work. You must also keep in your mind that life is to be enjoyed. I have found that a life without joy is a damnable thing and I ache for those who live it. For me, joy and adventure equate. By this, I mean that there should always be something you are struggling to attain, some great and perhaps mysterious goal, something outside the mainstream of work and family.
