Some of the best minds suggest that when you have a dream, you should keep it to yourself. You should set about quietly achieving your dream, but without sharing it with others. Their reasoning is that when you share your lofty goal, you open yourself up to the ridicule and criticism of those who say, "It cannot be done." This is distracting, and can negate your efforts.
Avoid the crowd who says, "It cannot be done." Instead, spend time alone giving your dream a form. Imagine what it will feel like when your dream has been achieved. Picture it happening. Decide what actions you must take to set your dream in motion. Finally, "just do it!"
You'll find that you don't need the adulation of others when your dream becomes reality. Just knowing that you caused it will be enough. True - others will wonder how you accomplish so much in life, while they seem to struggle for the slightest movement forward. So be it.
As the Disney theme song says, "When you wish upon a star, makes no difference who you are. Everything your heart desires will come to you!"
