As a rookie its your job to

1. ) Bring Energy, everyday

2.) Be positive 

- points 1 and 2 are something you can control when, as a rookie, you can't control much. You can chose your attitude everyday and show up to the arena ready to work with a competitive and  positive attitude. Show you're not bigger than the team or league. 

3.) Earn the trust of your coaches

- As a coach, you want to play the players you trust. Likely, those are the vets until a rookie proves they can take those minutes away from a vet. It takes time. 

4.) Earn the trust of vets

- Vets are on the team for a reason, because they earned the trust of their coach and figured out a way to survive in the league, show respect but be confident and fight for your share of playing time.
