I chose prompt #2.  I will be writing about "No knot unties itself" and "Opportunity is not a lengthy visitor."
"No knot unties itself"
When a person ties a knot, they are intentionally attempting to tie the strings together to make a bow or a certain type of knot.  String is lifeless and will not magically untie itself.  In life, I relate this to problems.  To create a life problem, choices must be made or actions completed.  Maybe the person says something they did not mean to say or they touched a hot stove.  Although those examples are very different, both will result from the actions of the individual.  Essentially, if a person creates a problem, they have to get themselves out of it.  If the person says something they did not want to say to another, they must confront that person and apologize or do all they can to fix what damage has been done.  With the example of touching a hot stove, the person cannot undo it or untie the knot.  The only way to fix it is to tend to the wound until it is healed.  There is no magical way to fix problems once they are created.   From the show, Into the Woods, the father of the baker steals the witches magic beans.  What happened then? The witch cursed the home of the baker and no one who lived in the home of the baker could have children and he had to give his first born child to the witch.  I say those are some consequences to his actions! The father of the baker works incognito to help the baker lift the curse in order to have children.  With the baker, his wife and the father all working together they are able to make right what was once made wrong and the curse is lifted. 

"Opportunity is not a lengthy visitor"
Opportunities sometimes require hard work, other times they are presented by chance but either way they come about, they are there for a short time.  A person may work extremely hard for a certain job and luckily, they receive a job offer.  The job offer will not be there forever, it must be acted upon immediately and the person will choose to accept or reject the job offer. An opportunity will be accepted or lost.  It will not be there if they reject it and then change their minds. At times in life, something may be presented that the person did not see coming.  No matter what it is, time and life will not stand still until they decide they want to take the opportunity.  That is why opportunity is not a lengthy visitor.  Technically, the individual must decide if they want to take take the opportunity or not and once time has moved on, there is no going back.  People need to know what they want and go for it.  Take chances that may lead to great opportunities, if they do not they will never know what they missed!  Rapunzel is faced with the opportunity in the woods to go with the prince or to stay with her controlling witch mother.  The viewer can tell that she thinks for a moment about going with her mother but then she remembers what is was like and she takes the opportunity to try something new! She decides to stay with the prince.  Rapunzel will be starting a new life with him, the twins and she will be experiencing a new sense of freedom that she has never felt.
