Life as a box of chocolates
Life was like a box of chocolates. You never know what you're gonna get.
Mrs. Gump in the movie - Forrest Gump
If we never know what we are going to get, does that means that we don’t try. No! Just try and try till we get the chocolate we want. Even if we have tried the whole box, go out and get another box.
Even if we can’t get the chocolate we want after several boxes, we know we have try and we have taste a lot of different kinds of chocolates. At least we know what different chocolates taste like.
