You become a pro soccer (football) player if you practice hard and follow your dream. Join as many teams as you can handle that way people will see that you have skill and are really passionate about the sport and when someone that can get you on a professional team hears about you then I guess your in. Good Luck.
I'm 14 also and my favorite team is Mexico.
I encourage you to join summer leagues. Also, I highly recommend you to join your high school team. Many high school players then go to play on to college.
From here if you are good enough you will probably get noticed and given a try out with a professional team here with an MLS team. Good luck!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
