Joseph had his dream and work towards it and he achieve it. Some of us had a dream but we forget it and neglect it. Never abandon your dreams, some dreams takes a long time before coming to pass, never give up.
The more we realize a man without dreams ain't existing, the more we take dreams seriously and understand that we ought to dream it before we can make it.
The quality of your dream is based on the quality of your spirit and in turn the quality of your spirit is the quality of the word of God you feed your spirit makes up the quality of your spirit.
