How to accept challenges in life?

You are thinking in your mind Why are these errors so prevalent upon the earth? 

It is because there must be something to rise above—something to give an incentive to struggle ahead, for the meaning of life in every sphere is advancement, and if there were nothing to overcome and escape from there could be no advancement—so troubles and trials are placed about (hu)man to urge him to make the struggle to overcome—to strengthen him—to teach him that there is beauty beyond to look forward to and strive to reach something ahead—to gain by honest thought along lines of cleanliness—to ennoble the mind and make it worthy of the Great Hereafter, which is so wondrous fair and beautiful.
