One thing I've come to realize about people is that most have never stopped long enough to come to terms with what their dream really is. A lot of people copy other people's dreams because they haven't taken time to seek God for their own.
Author Renee Swope in her book, The Confident Heart says,
"All men dream but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find that is was vanity. But the dreamers of the day are dangerous men, for they may act on their dreams with open eyes, to make it possible." T.E. Lawrence
Dreaming is dangerous because when we are fulfilling our God-dream and purpose we have such power to change the world.
