I think that the quote "A difficult challenge brings out the best in people" has many different meanings. But, the most sensible one is that by being challenged, you are able to hone your skills. Having a life with no challenges is probably some people's dreams,because life would be so easy. The thing that these people don't realize is that having no challenges will deprive you of the success that you deserve.
This is like the Hunger Games series. It is like this series because if Katniss, the main character of the hunger games, had not have had her father die she would not have hunted in the woods for survival she would have died in the games. The challenge for Katniss was her fathers death and her being on the verge of starvation. If she had not plowed through these troubles she would not have started a rebellion.
This is also like the Harry Potter movies because Harry had to get through the death of his friends. Since he went past it, Voldemort had not had been able to take over the world. This relates because if Harry did not have challenges he would not have had the ability to save the entire wizard world and his friends.
Having challenges has also helped me in life. The biggest reason isbecause I used to not study for tests until last year when did not get the usual A. I was so disappointed, that I vowed to study hard for tests. If I had not done poorly on that test, I wouldn't be getting the amazing grades that I have been getting so frequently.
I wonder what would have happened if I had done well on that test? If I had not realized that I needed to study for tests until it was too late? How would my future be affected by my terrible habit? I am so thankful that because of challenges, I will never need to ask all of these questions. That's why dreams of no challenges is more like a nightmare.
