The most important thing is to just start playing, and not be a big PUSS. I think as long as you don't flinch, try your best like a monkey to make saves, you will not get made fun of. Also, one must want to get hit with the hard shots, love getting bruises, and slide on their knees. Angles, reading plays, and all that good stuff comes with time, and some good suggestions in previous posts about using YOUTUBE n all that. Enjoy, because its a mind f*** playing in net aka crazy goalie syndrome.
