Impossible cases are not forever. While it is impossible for one person, it is possible for another. In a word, everything is possible. Someone says, "Success belongs to those who can look at the complex challenges offered by the world as inspiration." So your challenges are golden opportunities for success. How can there be miracles if there are no obstacles? How will you chase the storm if there is no storm? You need challenges to reveal your ability. Success doesn't come out' of nothing; success comes from the problems you face. Those who refuse to give in come out smiling. Robert X. Perez says, "The seeds of success spring from failure's ashes. "Failure is not defeat; it is the pointer to do better than what you just did. You have to know that you are in a constant study of life. What you face is for your training. Samuel Aidoo says, "Each failure is simply another chapter in the story of our lives. To fail is to understand what not to do. Remember it and don't give up until your goal is achieved." What do you do when you face difficulty? Yeah, life is difficult, but you do not give up. Have a positive and calm outlook on your circumstances   and make the best of them. You may learn something new. You can develop mental toughness. Mental toughness means to be able to see the long-term gains rather than be put off by short-term pains. Once you have this toughness, you have the winning edge . The only things in life you ever really regret are the chances you didn't take. You will regret when you see the consequences of not seizing the opportunities when they arose. Take chances every day! The main point of the passage is that  _  .
success comes out of nothing never give up and you may achieve success everything is easy to deal with impossible things do not exist
