Hi Mark, not much I can say that hasn't been said, but I agree, don't concern yourself with the average as it will come down in time.
I like your attitude and see you will like this game and your post made me smile and think back to when I started - as yet I still haven't managed to kick start a brilliant career, maybe I am just a slow learner lol, but I do love playing the game. You form friendships with people all over the world, have some laughs (often at my expense) and very occasionally (well virtually daily) wonder why the heck do we like this game.
The important thing is to enjoy the game, make sure you read the Putting and chipping tips under the FAQ and read the forums - there is a wealth of information in here.
The other really good news is, your scoring will only get better :))
