LIFE is like a roller coaster; it has its twists, turns, ups and downs. The ride is like an unknown adventure until we experience it. Once we experience it we want the thrill of being challenged knowing it may cause a wave of emotions. If we get on a ride but hate every minute of it we claim we will never go through that again; circumstances may change our minds given the situation.
We can't take out any part of the ride as it was designed that way.
