I watched this video and it made me wonder how many of all these different athletes had failed and what type of adversity they faced on their way to the top of their respective sports. I think kids look at athletes in their prime and see all the fame and popularity and have a hard time understanding the years of training to get to where they are on TV. First you need the vision, then you need the discipline to keep getting back up every time you fail, because if it is something worth while, it will not be easy and failure will come. It will force you to persevere….or crumble, that decision will be up to you. Unfortunately, alot of people end up crumbling because they aren't willing to sacrifice for what they want. Don't be afraid of failure, it builds character….
