Life often times throws us challenges that we have to over come. It isn't the challenge that defines us, it is how we respond to the challenge, how we move forward. One of the most inspirational things I have ever heard, was a motivational speech during a movie from a father to a son. "It isn't about how hard you can hit, its about how hard you can get hit and keep moving forward...But you gotta be willing to take the hits. And not pointing fingers saying you ain't where you wanna be because of him, or her, or anybody" - Rocky Balboa (Sylvester Stallon). This is a tough lesson that we all need to understand, life isn't going to hand you what you want, and there are always going to be things in your way. What really matters, and what will define who you are is how you react to those things.
This is the same in every aspect of life, sports, relationships, work, goals and everything in between. So remember, keep fighting, keep taking those hits, but don't let them beat you down. Keep moving forward and accomplish the things you want in life. Be who you want to be!
