You have to have performed a miracle, or lived a particularly good and God-filled life, and then wait for the Church to debate and discuss your beatification - that takes a few hundred years, so don't hold your breath!
It's rather heavy reading, but - if you really want to know the precise procedure involved - click http://www.catholic-ew.org.uk/mi/canoni01.htm
The problem, as far as CVs go, is that you have to be dead to achieve sainthood!
Sainthood can also be achieved by performing the absolutely impossible; - haven't like a dozen of them killed dragons or something? Perhaps a good start would be to finish a jar of Marmite, or train a fish to fetch a stick.
Look after my two kids for a day. Patience doesn't begin to describe the fortitude you'd require. I'd pronounce you St.Shelley no problem (it's been a long weekend!!!).
