Roller coaster called life

If you're someone who likes everything to go according to plan, you will be disappointed in life. In life everything doesn't go according to your plans. Today after I received a news that ruined all my plans, I realized life is a roller coaster. We don't know in which direction we are going. It is not certain, is unknown. It gets frustrating. Now I am trying to plan everything again and again.... Sorry for this confusing piece of writing. It is as confusing as life...
