style and discipline

In the morning I'll be preaching at a local church; 2 services.  I'm not used to doing back to back services.  Much of my style is setting up a discovery process which I do with people.  How does one repeat that back to back?  One doesn't, so I guess I'll need to be more disciplined in having my discovery happen in private and my delivery in public.  Not sure if I dislike that because I have a special style, or if it is laziness.
