My first post and already asking for help

I have loved card tricks since I was a kid and recently began take up again the joys of magic and illusion. The ID and svengali decks blow my friends away but I wanted to take it to the next level. I ordered "Showoff with cards" but I am really struggling with even the early demonstrations.
I have very small hands and wondered if this is holding me back or whether I have just gone in at too high a level. Any advice welcome...
