Being the best of the best at one time when he was younger everyone believed in him. Everyone. Once he started failing, people started to lose that belief in him. Everyone including himself. That was the hardest part for him. He didn't believe in himself. So he stopped doing what he once loved...playing the game of baseball.
Being in a different position later in life in the sport he loved, he had to regain that confidence. But the confidence he once had in himself, he now had to have that in the players that he signed to play for his team. The players he would be signing to his team were players that were in the same spot he was in many years ago. Players with no confidence for some reason. Players that no one wanted. Players that were told they had no shot.
The biggest thing that he learned and accepted was that if you really believed in something, no matter what it was you could do it. And it was the right thing. He had one person that believed right along with him. Everyone else balked at what he was trying to do. They all laughed at him. Told him it wouldn't work.
This is what I got out of this movie.
What does it take to make it happen? And by *IT*, I mean anything. All it takes is the idea or dream you have and YOU. Two things. That is all it takes to make it happen. Have you ever had something that you really believed in and people doubted you? All you have to do is believe in yourself. And if you believe in yourself, you might even find others that believe in you too. Confidence is key. It can either make your or break you. You have it or you don't. If you have it, it can be spread to others. People know if you are confident and can see it, feel it, feed off of it. If you don't have any confidence then people can sense that too. The greatest thing about what I'm trying to tell you is that this is true for both adults and children of all ages.
Billy Beane believed in himself and what he was trying to do. That is why it was successful.
No matter what you are doing or trying to do, if you believe in yourself...
Then you can make it happen.
