You are the lead actor as well as the director of your life. Apart from you, there are others characters in your life a well.
Now look at your life.  Who are these other actors and co-actors?  Yes, you have guessed them right.  They are your parents, your spouse, your children, your grandparents, your siblings, your in-laws, your friends, your neighbours, your teachers, your club members, your colleagues, your bosses, your customers and your suppliers.

Now let us zoom in, at random.  You may have a difficult colleague who is a pain in the neck.  She is grumpy and flares-up at the slightest matter.  Worse still, she is domineering and likes to boss around.  You must be thinking, how unfortunate to have her in your life.  Believe it or not, she is here for a reason.  She has been sent by the high-powered director to deliver lessons to you.  Probably on tolerance and empathy.  Do not judge.  Do not label.  Try to put yourself in her shoes.  See where she is coming from.  Understand why is she behaving in that manner.  Try to see the lessons she is bringing you.  Then get on with the lessons.  Until you have learned the required lessons, she will be here to stay.

A new chief comes on board.  He implements drastic measures.  He downsizes the company.  He issues punishing deadlines.  Yet he is fickle-minded.  You cannot take his nonsense and decides to leave the company.  Don’t bear a grudge against him.  Instead, be thankful.  He is here for a reason.  He is here to force you to take actions.  You may be comfortable in your current job.  But it may not be the right place for you.  He is here to help you move to a better place, a place that is truly your calling.

Think about the people in your life.  Past and Present.  Think about their roles in your life and the lessons they bring along.  Have an open mind.  It may just turn out to be a significant discovery.  A turning point in your life.
