Ralph Waldo Emerson said: People only see what they are prepared to see. Try to see what is invisible to others. Recognise the hidden potential. Create a vision, believe in it and aspire to it.
But that's not enough. W. Clement Stone said: There is something more important than believing: Action! The world is full of dreamers, there aren't enough who will move ahead and begin to take concrete steps to actualize their vision. Have the courage of your convictions. Be brave and take concrete steps to realize your vision.
Think about vision, courage and taking action when someone says "Oh that wouldn't work here."
