Unsolved Puzzles

Life is like a series of puzzles that you would stumble upon every now and then. In rare occasions, the key to the puzzle is as clear as black vs white. However, most of life's questions come in shades of grey, where the answers elude even the most inquisitive person. It is at such times that some chose to move on with a partially solved puzzle, and some who prefers to stay at that point making continual attempts at the puzzle.
