I'm 15 and I have an important football trial coming up any advice for mental and physical?

prepare yourself for the hardest challenge you have ever did the first thing you are going to have to do is man up mental and physical.hope you have been working out wts. and running this game is about a lot hitting and running and being smart .just make sure you are prepared and know what you are doing .discipline yourself and accept this as the hardest challenge you ever had to do.give the hits dont take them running the football you can give the hits instead of taking them there is no rule thats says you have to take the hits.with the football in your hands you can actually tackle them as long as your elbows knees helmet shoulders hips dont touch the ground .you can keep going and it is not a penalty as long as you are the ball carrier so give the hits dont take them good luck.
