30 is not many tries. I try to WILD (5 times a night X 7 night =) 35 times a week and I have 1 or 2 WILDs a week, and this is with almost 3 years of practice. (5 times a night X 7days a week X 52 weeks in a year X 3 years = 5,460 tries).

I would recommend checking out the guide that gab sent you to as well as these:
