Hi
if you choose file / new there's a number of different templates included -
maybe pick one that relates to your industry / experience, i find it's
always helpful when you actually have some idea of the data .... if none of
these seem suitable email me direct (julied_ng at hcts dot net dot au) and
i'll be happy to send you a file i use in training which has only about 20
tasks.
if you're just starting out with Project i would suggest having a read of
Mike Glen's excellent series of tutorials at
www.tinyurl.com/2xbhc and
signing up for a 2-3 days hands on project training course in your area.
Regards
