Im the same... You just have to forget about it, I dont like skateparks as there are people there that are soooo much better than you, and when you see people who are like 10 and stuff doing 360s out of bowls and things you dont feel too inclined to do something.
best thing to do is forget what might happen, think positive, and then think of the worst thing that will hapen... Thats what i do, I think, if I fall, it'll hurt a little bit, if i do it it will be great...
Lets go and usually i go just like that then..
You also shouldnt sit there and look at what your going to hit because you will become afraid of it.
