Struggle is what builds character in a person, and their ability to overcome or be overcome by it. Nobody wants to experience pain, suffering and loss but those are the critical ingredients to success in this world. You must learn your lessons in life just as you must in business and this typically comes from failure. Essentially, you don't know what you don't know... the unknown unknowns which pop up and create havoc. By learning how to navigate uncertainty and by creating realistic expectations you will fare much better in society.
