Question about being good at roller hockey.

Well I am trying to find a league to play in but all the leagues are an hour form my house, there is only an inhouse league 20 minutes away. I am joining this league but really wanna play travel...to improve. Which leads me to, how can i get better. After not making my highschool team this year as a freshman I decided my true passion was roller hockey. Now that I am playing I wanna play as much as I can and at the highest level I can play that will help me improve and at the same time still let me enjoy the game. I wanna play travel but all teams are 50+ minutes away. I might tryout for my statewars team though...its in the summer so transportation might be easier for me. I know the teams are competitive, so what can I do to prepare for it... I really wanna do something with roller hockey because I am very passionate about the game.
Any help is really appreciated
thank you
