Can i become a good winger?

it ultimately comes down to what position you know best, and which you like playing best. If wing is your style go with it. You could become a big, power forward, based on your size (which i personally think is exaggerated for a 12 year old but...). If you dont like the wing, try out D, and if that doesnt work, centre. Whatever fits you best.though skating is a good aspect of the game, its not the only one, so try and improve as best you can, otherwise, just keep playing
