Nietzsche talked about the elements that human beings naturally needed for a fulfilled life. He also talked about how to achieve this elements and he mentioned that it was impossible to attain them without feeling very miserable some of the time. "What is pleasure and displeasure were so tied together that whoever wanted to have as much as possible of the must also have as possible of the other.. You have the choice; either as little displeasure as possible, painless in brief... Or as much displeasure as possible as the price for the growth of am abundance of subtle pleasures and joys that have rarely been relished yet? If you decide for the former and desire to diminish and lower the level of human pain, you also have to diminish and lower the level of their capacity of joy."
Nietzsche explained that when you are in your journey to be happy and successful you must have had experienced jealousy. Stubbornness, mistrust, hardness,a variance, violence, among others. "Because no one is able to produce a great work of art without experience, nor achieve a worldly position immediately, nor be a great lover at the first attempt; and in the interval between initial failure and subsequent success, in the gap between who we wish one day to be and who we are at present, must come pain, anxiety, envy and humiliation...."
In another words, according to Nietzsche you have to fail a couple times in order to be successful, and all that pain and suffering is going to be worth it when you are at your highest point."
