Before you can even have the opportunity to throw the puzzle box of life away, you need to paint that big picture first. You need to know what you want in life, where you are going, and what that dream will look like.
When I put a puzzle together, I like to start with the edges and corners to fill the frame. Then, I like to put all of the pieces with the same colors together in groups. I allocate the pieces to the groups that they should go first.
