John,
I don't agree. I spend more time in creating my own patter and method, than I do in learning a trick.
I prefer to learn the workings of a new trick and then muse over my own ideas of the patter and story to accompany it. This may take me several weeks and its enhanced by performing in my local pubs and changing and adapting my original ideas as I do so.
I think that the creativity of your own mind and the way you adapt a trick to suit yourself and the way you perform it is as much a creative skill as the actual performance. Don't steal someone else's method, or change it, develop your own. I can't tell you how to do that, just be creative and think of your own ideas. If you can't do that, look at other peoples methods of performing the effect, not to steal it but to develop your own ideas on how to develop your own performance.
Anyone can learn how to do a trick, but good magicians make it exceptional by their own routine and patter.
PM me if you are struggling on this, its an art which takes you from a run of the mill magician to someone who is different
