That my friend is called the "American Dream"
Sadly most people have lost sight of that. I have a nephew also chasing his dream. He's now playing Jr A hockey in Canada, even after they all said he didn't have a chance! (not me!) He's had his dream since he was four years old, and now at nineteen he's getting closer to making it come true
If you want it bad enough I say Go For It
