Newbie requires advice

[SixteenSixtySix]

17 this year, 68kg give or take 1kg, 178cm tall. I've only played twice so far (both friendlies); I played as Blindside Wing; not my favourite position and I'm not really good at it as I'm not fast but my coach put me there because I can (sometimes) go through defences and tackles hard. I'm not very good with tactics and I usually just run the ball and gain as much ground as I can. As I think I might be playing as wing some more, any advice for me? What should I focus on in training and off? Also, with the lack of tactical, can I still play as a center (wouldn't mind as outside)?

My 2 cents;
Don't miss tackles;
Run hard, drop your shoulder when go into contact;
Only use a drop punt, don't try the spiral punt;
If centre, run with the ball in 2 hands out in front;
Talk a lot on the field even if you're shy.
