We tried to make it fun for our son.
He had a couple of kid's books about the potty, and liked to have them with him while sitting on the potty. We always had him take off his pull-up while on the potty (sitting bare bottom only). We didn't scold him if he wet his pull-up, but excitedly reminded him that maybe next time he has to "go", he can try it on the potty.
He got little stars (silver for PP, gold for poop) when he went in the potty, and was able to earn prizes when he saved up enough stars. We made him a little poster with cutouts of the different prizes he could get, and the number of stars required to earn them. This was posted in front of his potty.
Once he was pretty good about using his potty, he graduated to using the toilet, with the seat to his potty (which was design for this transfer) positioned on the toilet, for his use. When he was ready to stand and PP, we got those little toilet targets. :-)
